Sharon O’Donnell may regret inviting the Prime Minister into her new home.

Cameron was there to promote to the government's Help to Buy scheme, which helps underwrite mortgages on houses worth up to £600,000.

Sharon had taken advantage of this scheme and spent a morning talking to TV cameras and reporters about how it had helped her.

Two days later an anonymous blog was posted online, apparently exposing the visit as a PR scam.

The takedown went through Sharon's background step-by-step.

It was damning stuff and swiftly went viral on Twitter.
