The official Twitter account of the Prime Minister has been following the exploits of a high-class escort agency, it has emerged.
But Downing Street indicated that the agency - which is no longer followed by the Prime Minister's account - may have first been followed under Gordon Brown's premiership.
Carltons of London claims to be London's "finest luxury boutique escort agency" catering for the needs of a "select and small group of elite gentlemen".
The agency also offers a corporate service for those looking to secure a big deal who "need something special to swing them in your favour".
The @Number10gov account is the official Twitter feed for the office of the Prime Minister and automatically followed anyone that chose to follow it until 2009 - while the former Labour leader was in power - when the practice was stopped.
It is not the first time the Prime Minister has fallen foul of Twitter. In September the Prime Minister's official Twitter account - @DavidCameron marked a highly offensive tweet as a "favourite" on the social networking site.
