The Lib Dems are guilty of breaking their promises to voters - on VAT, tuition fees and police cuts.
They are guilty of colluding with the Tories - on tax cuts for the rich and tax credit cuts for low income families.
And they are guilty of duplicity - purporting to protest against Tory-led Government decisions which they have voted for, and which would not have been able to be pushed through without the votes of the Lib Dems themselves.
They have been caught yellow-handed and we are warning people not to trust them again but to vote Labour on May 3rd.
Today I launched a document exposing how the Liberal Democrats are saying different things to different people in different parts of the country: Caught Yellow-Handed.
