One of the things that makers of electric cars need to improve to encourage more  potential buyers of them is their range and how easy it is to refuel them. Because the battery needs so much power to recharge it can typically take 12 hours to recharge a near flat battery from a domestic mains supply. It means some use electric  cars as short distance transport to and from home so they can rely on the long overnight charge.

If they wish to travel longer distances owners need to plan ahead to see where there are  fast chargers available, or whether there are overnight facilities where they are going that would allow the usual long overnight charge. Some of the charge points now available do not have the right connectors for every type of electric car.  Tesla has their own network. Apparently you can face the need to download an app, supply a lot of data and enter into a supply contract with monthly sums if you wish to recharge at some charge points. This is more intrusive and complex than simply buying a few litres of fuel for card or cash.

Gradually more charge points will be installed, and possibly more will accept the range of vehicles and charger links they have on them. There is then the issue of how long it takes to put enough charge in to the vehicle to continue your journey. I can refuel my vehicle in five  minutes to give another 450 miles range from anyone of around 20,000  filling stations. This is convenient. Even with a fast charger you will not get anything like  450  miles of range for 5 minutes at the filling station.

There is also the issue of effective range. The electric car will give you an estimate of how far you can travel before a new charge. This may prove optimistic. If you get into heavy traffic, if it starts to rain and you need wipers, if you need the heater or if the light wanes and you need lights, your effective range can contract visibly.

Many of us want clean air. In past ages people paid a health price for industrialisation, and for keeping their homes warm with coal fires. Soot, particulates, smoke and dangerous gases came from factory chimneys and from domestic heating and cooking.

In more recent times there has been a successful and concerted effort to clean our air. Coal fires were replaced with gas and electric heating. Factory chimneys are now strictly monitored and dangerous emissions are contained or rendered harmless.

The Green movement urges us to do better. They would like us to switch away from gas boilers at home, and wish to cut the impact of transport on air quality. If you live near a main road or major airport or railway line with diesel trains there can be dirt in the air.

The issue of small particles of material that can damage lungs is no longer a question of too many diesel cars as some suggest. The modern Euro 6 standard diesel car is only allowed to put out 0.0045gms per km travelled. This is such a low level that it is difficult to measure whether it is there or not, and is the same limit as for petrol cars. There are still some old diesel buses, lorries and cars that do emit higher levels of particulates.

The more important sources of particles from transport now comes from tyre wear and brake dust. These are often more severe in heavier vehicles. Buses and heavy trucks are likely to generate more than a car. Electric cars generate at least as much as petrol and diesel, and if they have heavy batteries for range and performance reasons they may create a bit more tyre wear from greater weight. There are also dust and particles in tube stations and mainline stations. The quantity of tyre and brake dust may well be more than 1000 times higher than the tiny amounts from a modern diesel or petrol exhaust.

It would be good for more work on tyre materials and brake friction to see how these particles can be reduced. Switching to electric cars does not fix this – it is a common problem for all transport. Even a bike has brake pad and tyre wear.

Yesterday in the Commons the Culture and Digital Secretary announced a change of policy for the roll out of 5G mobile telephony. Following new official advice on national security , the government decided to ban Huawei components in the 5G network from the end of this year, and to work away to remove Huawei altogether by 2027.

The government accepted this would delay provision of the new network by between 2 and 3 years and could cost an extra £2bn. The Minister given the job of explaining this stressed that national security must come first, so this was a necessary price to pay.

This was a crucial moment in the evolution of UK policy. It marked a decisive departure from the pro China approach of the previous 15 years, where buying more them whatever the degree of sensitivity of the product or component was fine. Our policy towards China was based on the proposition that they would do us no harm and be there for us when we need their supplies. It was a grand partnership where we became more dependent.

The immediate trigger was a tougher US stance limiting Huawei’s ability to make and export. The further deterioration in the relationship over Hong Kong, the treatment of minorities in China, the aggressive approach to the South China Sea and the action on the Indian border also influenced the decision.

The UK needs to have enough control over strategic networks and over crucial intellectual property for our wider security. Immediately the UK needs to catch up with the leaders in mobile telephony.

I am urging the Chancellor to say that anyone undertaking home insulation, buying double glazing, improving the energy efficiency of their homes should be able to claim one of the new Green grants for work underway since the announcement.

The Chancellor proposed £5000 per household by way of a grant to cover a possible two thirds of the cost of green energy projects undertaken. The short term problem is people are delaying or cancelling projects they were planning until the terms of the grant are clear and they can apply to get the money. More is on offer to people on low incomes.

It is one of those ironies of life that an intervention in the market designed to be good news to boost certain kinds of home improvement should lead to cancelled work owing to understandable delays in setting out the detail of the scheme. All can be put right by a helpful immediate statement, allowing applications for grants to follow commitment to the work this week. This will keep the orders flowing for an industry just trying to get over lock down and temporarily closed businesses.

Yesterday evening the Commons approved the Bill to cut Stamp Duty. There, contrary to some press stories, the government brought the measure in straight away and legislated afterwards. Otherwise the big temporary cut in Stamp Duty would have set back the housing market by putting people off buying until the tax cut came in. It is good news for first time buyers and for those wishing to trade up their primary residence that no Stamp Duty is payable on £500,000 of any purchase. This means 90% of all homes will be Stamp Duty free for those buying them as their prime residence.

Today the government’s extended consultation on Freeport’s closes. It is time to press on with this excellent idea to boost investment growth and trade.

The old idea of a Freeport was a limited land area around a seaport where planning controls were relaxed to encourage and allow value added processing of imports for their re export as finished goods. There could also be tax incentives to boost activity further.

Today we should be thinking of the virtual Freeport spreading out further from a seaport or airport to create an economic zone or area dedicated to manufacturing and adding value added through services to foster exports tax free. The free port zone could also be a place to manufacture or add value to goods and services for the home market, where any tax and regulatory compliance took place at the time of completion and transport to market.

I would like these wider zones to offer a five year business rates holiday, entrepreneur’s relief from CGT, no Stamp duties and of course no VAT or tariffs on anything for re export. We need these industrial development zones in all parts of the country, so let’s press ahead with 10 straight away with good geographical coverage.

To some the full relaxations of rules imposed to fight Covid 19 cannot come soon enough. I have varied complaints from people who strongly object to what they call house arrest. They think it would be better to isolate people with the disease, and offer support to allow people most vulnerable to the disease to limit social contacts, rather than asking most of the population to stay at home. To them freedom is the freedom for the many to have a social life of their choosing, to travel as they wish, and to run their  businesses as they see fit. They argue if we do not get back to this soon there will be unacceptable economic damage.

To others freedom is the  discovery that they can work from home, draw their full salary, and avoid the 3 hour return commute each day. They say their lives have improved. They are no longer dependent on the erratic goodwill and competence of the train companies, and  no longer have to push themselves into a crowded tube train or onto a bus to complete a city centre journey to work. They can mind their house, receive deliveries, see more of their children and still do their job using on line facilities. They say there can be compromise between fighting the virus and getting the economy moving. They want new working  practices which can pay the bills and keep people safe.

To some the idea that their every move may be tracked, and they may be subject to a tracing system requiring them to self isolate because of a chance encounter with someone who had the disease is an unacceptable intrusion into their lives. They are suspicious of how likely you are to catch it from casual contact.  To others a proper track and trace system is essential to give them more chance of escaping the virus. They wish to be free from disease.

So where does freedom lie? Have the anti Covid 19 measures simply taken freedoms away, leaving us with arguments about how successful this is in controlling the virus? Or are there some compensating freedoms some have gained? What should the new world of work look like?

Some universities are said to be in financial trouble. It has arisen because they have expanded, offering many places to overseas students, only to find that model  poses difficulties at a time of retrenchment for international travel and exchange. Over reliance on Chinese students could be especially difficult. The deteriorating relations between the West and China over civil rights in mainland China,  the new Hong Kong law and the intellectual property issues may put some Chinese students off coming . It would be good to hear from the university representative bodies what they think about the extent of China links, and how they respond to the current Chinese policies on human rights and intellectual property.

Universities have also entered the academic end of the leisure and entertainment business, offering informative conferences during the breaks  between terms. These have stood empty for months with a substantial loss of income. They have invested in student accommodation, which has also been without tenants during the lock down period, leading to further income shortfalls.

The university establishments receive substantial research grants from governments, and some from companies for research that their sponsors wish them to carry out. The system of peer reviewing is said to be a strength, where research is assessed by other experts in the field who have the power to publish and recognise it or to mark it down and keep it out of the respected journals. Having a quality control in one sense is a good idea. There is however the danger that it encourages me too thinking, where a younger academic has to proceed around the work of a better established academic, without challenging the foundations of what the elder was doing. It can create groups of like minded people training up a new generation to think the same.

It also knocks on to governments procuring research. The senior academics are likely to influence the grant awarding and commissioning bodies in the public sector, pointing them in the way of research that bears a family resemblance to what they have already done. It can just be a case of the academies corralling around their fashionable theme or theory, seeking to prove it and extend it, whilst keeping out any serious challenge to it.

Government should look carefully at what research it is commissioning. There is no need to commission more research to extend or prove things academics claim to know. There is more need for research which pushes the boundaries and challenges some of the tired assumptions of current thinking.

I have no problem with the idea that a quoted company can be bid for by potential new owners who value it more or who might run it better than the existing owners. I do have a problem with the U.K. offering this freedom to countries and companies who do not accept the same discipline. I particularly oppose the idea that nationalised industries or foreign states should be able to buy up U.K. based businesses.

One of the unfairnesses of the single market was we offered up most of our large businesses for sale to France and Germany but they offered up very little of theirs in return. Cultural obstacles, different ownership structures, EU rules and Court judgements and different national government approaches meant during our time in the market many of our companies were acquired from the continent whilst U.K. companies made little or no progress with either acquisition or organic growth strategies in the leading EU countries.

Just look at what happened to our building materials industry for example. In the 1970s we had large advanced companies mining China clay, producing cement and ready mix concrete, making tiles, kitchen units, glass, plasterboard, bricks and tarmac. They did pioneering work on ready mix, concrete tiles, glass and other processes. These items make sense to produce locally as transport costs are high and the travel intrusive. They created many jobs in the U.K. and did not add to the import bill.

Redlands tiles was bought up by French Lafarge. Marley Tiles was bought by Belgian Etex. BPB plasterboard was acquired by French St Gobain. Blue Circle Cement was bought by French Lafarge. Ready Mix Concrete was purchased by Mexican Cemex. Hanson Trust with wide ranging building material interests including bricks was taken over by German Heidelberg Cement. Magnet Joinery’s kitchens and other wood products were snapped up by Swedish Nobia. Tarmac’s aggregates and road materials were bought by French Lafarge. English China Clays was acquired by French Imetal. That just left Pilkington Glass with world leading technology to go to the Japanese, and our main scaffolding business to go to the USA.

In the case of the USA Hanson had acquired various materials companies as that is an open market. There were practically no successful U.K. bids for European companies given the constraints, apart from Braas bought by Redland only to be sold back to the continent as part of the sale of the larger group.

As we develop our own free trade and overseas investment policies we need to make sure there is reciprocal access for bids. In areas like defence, data and communications we also need to be aware of the needs of national security. There are some basic competencies and essential areas where we need a domestic capability. The extraordinary story of how the U.K. sold out of practically all its leading building materials shows what can happen if our access is blocked. Once you lose control of the assets you can then be taken on a journey to much more dependence on imports, where you export the jobs elsewhere.

The Chancellor yesterday set out how he intends to wind down the furlough scheme whilst encouraging employers to keep those employees and to restore their work. He also made some proposals to boost tourism and hospitality business, and to assist more young people into the workforce. I will post my short speech in the House on the economy later this morning.

This is your opportunity to comment on the current state of the recovery and government plans to stimulate it.
