PM followed escort agency on Twitter

Prime Minister David Cameron has been left red-faced over yet another Twitter gaffe, after it was revealed that his account had been following a high-class London escort service.

It is the third time this year that Cameron has been involved in a Twitter fiasco, having previously 'favourited' an offensive tweet about Foreign Secretary William Hague, and listed the spoof Twitter account @IDS-MP for Work and Pensions Secretary Iain Duncan-Smith.

The latest embarrassment involves Carltons of London, which describes itself as "London's finest luxury boutique escort service, tailored to the needs of a select and small group of elite gentlemen."

Coincidentally, the service shares its name with London's Carlton Club, "the oldest and most important of all Conservative clubs", but Number 10 claim that the inadvertent following came about as a result of an automated following system they had in place in 2009.

In a statement given to the BBC, a spokesperson for Number 10 said: "Prior to 2010, an auto-follow process was used, meaning that @Number10gov automatically followed anyone who followed the account.

"This was common practice at the time for many corporate accounts, but was discontinued in 2009.

"As a result of this legacy, the @Number10gov account follows almost 370,000 accounts and we have taken steps to un-follow as many as possible that are inactive, spam or inappropriate. This work is ongoing."

Earlier this year, the Prime Minister made a futile call for the general public to to boycott social networking sites such as Twitter, following criticism over cyber bullying.

A late-comer to the world of Twitter, Cameron once famously remarked, "too many tweets might make a twat."
