After news broke that popular Uxbridge and South Ruislip MP Sir John Randall will step down at the next general election, speculation that Boris Johnson will take over the seat for the Conservatives has escalated.
It has been rumoured for some time that the Mayor of London is hoping to make a return to the Commons in 2015, and leaving his seat means Mr Randall has opened the door for Mr Johnson.
The Mayor has however, remained tight-lipped on the issue.
His official spokesman said: "The Mayor is focused on delivering on his second term commitments - the continued creation of jobs and growth in London, the provision of new housing to meet growing demand, and the further reduction of crime in the city.
"We don't comment on rumour and speculation."
Councillor Wayne Bridges, chairman of the Uxbridge and South Ruislip Conservative Association said the news of Mr Randall's resignation was met with 'great regret'.
He said: "John has been an outstanding local MP for the past 17 years and has always put residents interests first. We wish him and his wife Kate well in their future endeavours.
"The Association will now seek an individual with the same passion and commitment to the local community, and will shortly be making arrangements to select a Parliamentary candidate as per the selection procedures outlined in the Party Constitution."
Labour's Prospective Parliamentary Candidate for the seat, Chris Summers, said he looks forward to finding out who he will be running against.
"I can promise them a hard-fought contest," he said. "There have been rumours already that Boris Johnson might stand and I would relish the opportunity to lock horns with him."
