The resignation of Menzies Campbell as leader of the Liberal Democrats is a shame. British politics is full of smarmy, crawling, grasping, conniving, poll-obsessed toadies who want only to be in power. Sir Menzies was a different breed altogether. Here was someone older, wiser, a person of diverse experiences - from Olympic sport to the armed forces - who could offer a different, more considered opinion on a variety of topics. Sadly, he wasn't young and photogenic (and vacuous) like David Cameron, nor sullen and combative (albeit clever) like Gordon Brown, so he chose to resign (or was forced out, depending who you believe). A new, younger LibDem leader will be duly selected, and the three parties will start to homogenize even further.
