I can see why Labour had to sack its Scottish candidate Stuart McLennan (twittering about how much you hate to visit your constituency is a little tactless) but does this mean that anyone with a colourful past (or a colourful blog) should forget about standing for elected office? Because if it does, it's a shame. There's a certain type of politician who's a bit of buccaneer- farouche, risk taking, careless of causing offence- Lloyd George, for instance, Churchill, Mo Mowlam- and we need them in the mix.
