As if her toe-curling appearance on Celebrity Big Brother was not embarrassing enough for her husband, Sally Bercow is to go even further.

In a move that is sure to further annoy her husband, the wife of Commons Speaker John Bercow is to share a caravan with Irish traveller Paddy Doherty, who won CBB, for a Channel Five reality show.

The pair will start filming When Paddy Met Sally in north Wales next month, with Doherty’s wife Rosemary moving out as 41-year-old Mrs Bercow moves in.

Mrs Bercow has previously admitted her husband was less than pleased with her appearance on Celebrity Big Brother, and her latest grab for the spotlight could bring further tension to a marriage that some say is already under strain.

It has not yet been decided whether Doherty, 52, will then move into the Bercows’ grace-and-favour Westminster flat.

The former bare-knuckle fighter was invited on to Celebrity Big Brother after appearing on the Channel 4 show Big Fat Gypsy Weddings. He made it clear he thought the 6ft Mrs Bercow, who has already shown him around Westminster, would get on his nerves.

He said: ‘I’m getting paid a few bob to live with her for a few weeks. I told the people when I signed up that I’m likely to murder her.

‘She better know that I can’t cook and clean. I can wash a cup but that’s about it. If she tells me to start cooking and cleaning, I’m going to kick off. I’ll teach her something about gipsy life, that’s for sure. She’ll know what travelling is all about when I’ve finished with her.’

Doherty said: ‘We got on diamond in the Big Brother house so I’ve agreed to come and let her live with me for two weeks.

‘I think me woman will move out for a week but not sure what’s happening the other way round, whether I’ll move in to the House Of Commons with her.
