SIR - Responding to a good letter from George Hitchcock saying the centrist principles in British politics served us well up to the 1970s, the problem was that that's where it ended. We then of course had Thatcherism and then even more significantly today, the Third Way starting in 1997.

This Blairite project was a pragmatic approach mixing and matching elements of both Conservative and Liberal thinking. For example, New Labour were right wing on foreign policy - some would say irresponsible - and their endorsement of capitalism, but left wing on the minimum wage, mass immigration, the promotion of multiculturalism along with the relegation of punishment for criminals.

Until now this has all become the mainstream political orthodox whether we agree with it or not. But now we're getting Brexit things could change again.
