Lib Dem vote set to collapse in south-west 'heartland', ComRes/ITV News poll suggests
Video report by ITV News Political Correspondent Romilly Weeks
A new ComRes/ITV News poll suggests a dramatic collapse in Liberal Democrat support in the South West - traditionally viewed as the party's heartland.
The poll, which looks at 14 currently-held Lib Dem seats in the region, shows a 13-point swing from Nick Clegg's party toward the Conservatives - potentially handing them control of each of the constituencies surveyed.
According to the polling, Labour, Ukip and the Greens have all also made gains as a result of the Lib Dem decline.
The poll also makes somber reading for Clegg personally, with three in ten people (29%) in these seats saying that the current leader puts them off voting for the party.
A further one in three voters (32%) in these seats - and 21% of people that voted for the Lib Dems in 2010 - responded to the survey saying that they believe the party has become irrelevant.
And while, traditionally, the Liberal Democrats benefit from popular constituency MPs who maintain support whichever party is leading the country, seven in ten (72%) say they will be voting for the party they like, not just the individual candidate.
ComRes polled 1,005 adults in the 14 constituencies for the survey.
The result comes after Nick Clegg launched the party's manifesto, which he called an "insurance policy against a government lurching off to the extremes" after the election.
