Tommy Robinson criticises Sadiq Khan's wife for putting on a hijab - except that's not his wife

Former English Defence League leader Tommy Robinson posted a tweet criticising Sadiq Khan's wife for supposedly putting on a hijab after her husband's election - except he got the wrong woman.

The tweet had "before" and "after" images of the newly elected London mayor's wife Saadiya Khan.

But the woman in the "after" photo was actually Sarah Joseph the chief executive officer of a media group.

Mrs Joseph commented on Twitter: "In his blind hatred Tommy can't tell the difference between Saadiya and me. Malice knows no boundaries it seems."

Her tweet has sparked numerous comments and has been retweeted more than a thousand times.
