This makes seven LibDem candidates to join the Conservatives this year, in which some LibDem blogs have been calling their "annus horriblis". However, I have yet to find a single LibDem blogger who has commented yet - as Iain Dale points out, if this was a spate of Tory defections the gloating would be deafening.
I said that the polls didn't matter for the LibDems but the trend does. This latest news certainly adds to that trend. Sir Ming might yet be in trouble.
