The first lesson is that nobody should be able to make £13 million on a project before it has even been built. Secondly, this whole thing is an outrage. People are being sold a pipe dream. Politicians who support it are being taken out for lunch, and those who ask difficult questions are being threatened with legal action by a group of expensive City lawyers. Some £9 million of taxpayers’ money has been wasted. The only infrastructure we have seen so far has been the £35,000-worth of work done to Mr Carrick’s mansion in Grantchester, and the only sports car in evidence is the Aston Martin that he drives around in. It is time to pull this project.
