The results of a poll showing Ukip surging ahead in the European elections are in line with a ComRes poll for the Sunday Mirror and Independent on Sunday last month, which put Ukip on 30%, Labour on 28%, and David Cameron's party on 21%.
The findings suggest Mr Farage has not sustained significant damage from recent furores over his expenses, "racist" posters, criticism of misleading campaign literature, and dubious comments from activists.
Former Tory donor Paul Sykes, said to be worth £650 million, has pledged to plough more money into Ukip after funding one poster campaign.
He told the Sunday Times there would be "at least another two waves" of adverts before the European elections."I'm not giving up," he said. "That will warn the Conservatives what is going to happen. We will get more democracy in Britain if it skints me."
