House of Commons Speaker John Bercow and his wife Sally Bercow attend a church service at Holy Trinity Church in Dalston, London, yesterday. Sally admitted on February 4, 2011 she had been a “complete idiot” in posing for a newspaper in a bedsheet. John Bercow’s wife Sally, 41, appeared in London’s Evening Standard on February 3 wrapped only in the white sheet, standing before a window overlooking parliament. Sally has raised eyebrows with her extrovert actions and her latest public appearance has heaped further pressure on her husband.
