In 1981 The General Post Office was split into two nationalised businesses,the Post Office and British Telecom. They both needed to modernise to adapt to the coming computer, communications and data revolution.
BT was short of capacity. There were long waits to get a phone installed and some had to share so called party lines. That meant if your neighbour was on a call you could not be. UK switching was way behind US, relying on electro mechanical switches when the US had gone electronic. The UK had copper cables, with insufficient reliable capacity for data.
The Post Office counters business was labour intensive and dependent on government business to handle benefits, driving and car licences and passports.
BT was sold to new shareholders in 1984. It changed over to electronic switching, developed mobile telephony, greatly expanded its network and allowed many more devices and services to be run over its wires.
The latest annual figures for BT show profits of £1.2 bn on turnover of £20.8bn. It invested an additional £4.9 bn in the year, extending its broadband coverage. It paid substantial taxes.
The latest annual figures for the Post Office recorded a loss of £414 m, with £133 m of investment paid by taxpayers.
What exactly are the benefits of nationalisation meant to be?
