The BBC have revealed that all contestants for Graham Norton’s new show ‘Totally Saturday’ are thoroughly vetted, to ensure they don’t have a Susan Boyle situation.

Susan had a very public breakdown after auditioning for ITV’s Britain’s Got Talent, the incident made BBC bosses look again at their procedures for guests on their shows.

Totally Saturday sees Graham Norton playing pranks, Jeremy Beadle style on unsuspecting members of the public.

A BBC insider told The Sun: “The order has come down from on high that they don’t want a Boyle on their hands.”

The insider added: “ Watching what happened on ITV horrified them. If anything that bad happened on the BBC it would have huge ramifications.”

Last night a BBC spokeswoman said Totally Saturday has a “great duty of care towards all involved in the show”.

She added: “The public are selected with extreme care and in line with BBC guidelines.”
