A front page story on David Cameron ruling out running for a third term as prime minister is getting attention for all the wrong reasons today.

Cameron was speaking to the BBC at his home in Oxfordshire.

Twitter users have noticed that in the far right hand side of the photograph splashed on the front of Tuesday's Daily Mail (24 March) there is a mystery figure peaking around the edge of the door.

There is also a video of the unidentified culprit, who quickly jumps back behind the door when realising that the interview is on air.
