Who doesn't support flat taxes?

Mr Seat asks if Gordon Brown and GWB are the last two people who don't support the idea of a flat tax. Having had a Labour blogger offering qualified support for flat tax on one of my own posts this is perhaps not as far from the truth as it might seem.

Martin Stabe reckons the reason for the Treasury's censorship of the FOI disclosure on flat taxes might be that it related to formulation of government policy. If he's correct then that only leaves Bush in opposition.

Bring it on.
