SALLY Bercow, the controversial wife of Commons Speaker John Bercow, could appear in Celebrity Big Brother.

The 41-year-old, who posed for a magazine shoot wearing only a bed sheet earlier this year, is believed to have signed with Channel 5.

However, television bosses will still not confirm the celebrities appearing on the new show and it is likely the line-up will only be revealed on launch night at Elstree Studios, Thursday August 18.

Sally Bercow is an outspoken Labour supporter, despite her husband being a Conservative MP, and is often criticised for undermining Mr Bercow’s role in Parliament.

The Daily Mail reports Conservative MP Rob Wilson (Reading East) to have said: “John Bercow said he wanted to restore respect and dignity to Parliament in his manifesto for Speaker.

“I am not sure how Sally Bercow going on one of the country’s tackiest shows helps.”
