The Conservatives have lost up to a third of voters who planned to back the party just four months ago, according to an Ipsos poll for the Financial Times that points to high levels of volatility ahead of the UK election on July 4.
The survey, conducted on the same cohort of almost 16,000 voters at the end of January and the start of June, found that 32 per cent of people who had said initially they would vote Conservative have since changed their minds.
Rightwing party Reform UK has attracted 8 per cent of the Tory voters polled, 6 per cent switched to Labour, while 7 per cent said they were now undecided and 9 per cent said they were less likely to vote at all.
