A public statement that it would be reasonable to expect that any "Liberal Democrat" with a shred of personal honour to make at this point:

"When I stood for election in May, I pledged myself to vote in the Commons against any rise in tuition fees for students. However in light of the economic situation I now feel unable to carry out that pledge. I will therefor be resigning my seat in the Commons, and standing as a candidate in the forthcoming by-election, this time promising to vote to raise tuition fees."
