If the government wants to plunge us into more debt to support investments, it is vital those investments make profits and pay the interest on the debt.
The government needs strong guardrails to achieve this. In each case they need to ensure
1 Any private debt added to a partnership scheme is non recourse to the taxpayer
2. There is a clear stream of future revenue from the completed project that covers the interest on the debt more than twice
3. They should set a minimum target return of say 4% above inflation and explain how this can be reached in the Business case
4 Management should be on a low basic salary with substantial bonuses if profit and cash flow targets are hit
5. The interest on the extra state borrowing should be a charge on the project or company being financed.Dividends would only be paid to the state when appropriate.
6. The state would ensure all necessary permits and licences are available to the project, subject to them meeting the required standards.
