The BBC has been forced to apologise after Strictly Come Dancing head judge Len Goodman swore live on air.

Len appeared to mutter the f-word after expressing his delight at a performance by Blue star Simon Webbe and his partner Kristina Rihanoff.

Presenter Zoe Ball (still replacing Claudia Winkleman) told viewers of the dance contest: “I also would like to apologise. Len got a little bit carried away with the excitement of the dance and I’m very sorry for the bad language.”

What language will Len use when he hears tonight’s results?

The Strictly Come Dancing results show is on BBC1, Sunday, November 16, 7.15pm
