It takes a lot to flabber my gast, but David Davis, the Shadow Home Secretary has just done it. I was driving home, and switched on the car radio, and there he was, making a passionate speech about the erosion of civil liberties. I was really enjoying hearing a reminder of why I've so long been an admirer and supporter of this man - when he suddenly announced that he was resigning as an MP, to fight an election on the issue of Britain being turned into a Police State. I was staggered.
Because of the way I've arranged my life, it's been difficult for me to become involved in by-election campaigns. But I will be with David as he fights a cause which I too believe in with a passion. The Telegraph may well report that 69% of the population agree with yesterday's vote to extend the period when an innocent person (until proven guilty) can be locked up - and to that can be added the power of the Sun. But David Davis was not prepared to stand by and watch the liberty which underpins our way of life being destroyed - doing the terrorists work for them. I've no idea how this decision will play out or be treated by the commentators, but I think it is a stunningly brave and principled decision.
