Speaking to workers at the Lib Dems’ Cowley Street campaign headquarters, Mr Clegg said the May 6 poll would be ”a huge, huge election” which would spell the beginning of the end for Gordon Brown.
He blamed the Prime Minister for the”rottenness and corruption” in Parliament and the failure to regulate the banks.
Mr Clegg said: ”It is a very exciting opportunity for everyone in Britain who wants fairness and real change, who wants something different.
”This isn’t the old politics of a two-horse race between Labour and the Conservative Party. The real choice is between the old politics of Labour and Conservatives and something different, something new and that is what we offer.”
Putting his thumbs up to applauding activists, Mr Clegg said the Liberal Democrats would ”give that different voice, that choice, which people have been lacking under a succession of Labour and Conservative governments”.
Mr Clegg said: ”This is a huge, huge election. It is certainly the beginning of the end for Brown, that’s for sure.
”Brown’s utter failure to stop the greed in the banks which has now created this recession and hit so many people so hard. Remember, (Lib Dem Treasury spokesman) Vince Cable stood alone in the House of Commons saying this can’t go on and neither the Conservative or Labour parties realised that we were right and they were wrong.
”It has become harder to get on under Brown and that’s what we are here to change.”
