Poll gives Boris constituency lead
More than half of voters in a London constituency seen as a prime target for Boris Johnson would vote for him if he chose to stand there in 2015, according to a poll.
A survey conducted in Uxbridge and South Ruislip after the London Mayor finally confirmed his desire to return to the Commons showed he could significantly boost Tory support.
But a third of those who backed the colourful Conservative also said he should quit City Hall if elected - despite Mr Johnson insisting he could see out the final year of his term.
The poll of 1,000 people in the seat being vacated by former deputy chief whip John Randall was carried out for Tory donor and former party vice chairman Lord Ashcroft.
Mr Randall held the seat with a majority of 11,216 at the last general election, making it a plum target for Mr Johnson, who has remained tight lipped about his preference.
The deadline for applications to the local party is August 28.
Lord Ashcroft said that when asked generally about their 2015 intentions, 42% of voters said Conservative, 28% Labour and 19% Ukip.
But when they were faced with the prospect of Mr Johnson being the candidate, the Tory share rose to 52% , with Labour down five to 23% and Ukip down three to 16%.
The peer accepted that the figures would be different if other parties put up a high-profile challenger but said Mr Johnson had a "unique ability both to galvanise Tories and appeal to supporters of other parties".
More than half (53%) said he was "different to most politicians, and in a good way" compared with only 7% saying he was different "but in a bad way".
Voters overall were evenly split on whether he should continue as mayor until 2016 if elected as an MP.
Mr Johnson last week declared his intention to stand for Parliament at next year's general election, finally putting an end to months of speculation about his ambitions for a return to Westminster.
It immediately raised the prospect that he could emerge as a rival for the Conservative leadership if the party is defeated - or again fails to secure an overall Commons majority - at the polls.
He remains behind David Cameron in terms of who would make the best prime minister by 36% to 33% - but well ahead of Ed Miliband on 19% and Nick Clegg on 10%.
