Which Labour MP has a tattoo on their bottom?

Tonight it's Labour MP and blogger Tom Harris's Birthday. Iain Dale is

twittering

that he turned down the invitation to join him and fifteen other Labour MPs for a Chinese and karaoke. Tom might have banned cameras from the event tonight but that hasn't stopped all sorts of gossip emerging from these shindigs in the past.

Last time this crew got together, another blogging Labour MP Kerry McCarthy

noted

that one of the MPs had drunkenly admitted to having a Labour rose tattooed on their left butt cheek. Just yesterday Tom was doing the increasingly irritating 25 random things meme that has been doing the rounds, but chose to

add some more facts.

Such as the fact he got his one and only tattoo after becoming a Labour MP...

And he doesn't deny it is indeed a Labour rose tattooed on this left buttock.
