'Britain's Got Talent' runner-up Robert White will target Simon Cowell on his UK tour with material too rude for TV.

The 41-year-old comedian left fans in fits of laughter with his scathing lines about the talent show boss and his fellow judges David Walliams, Amanda Holden and Alesha Dixon, and he's promised people coming to his upcoming live shows that he didn't even scratch the surface.

Speaking to the Daily Star newspaper, he said: "I know people will be coming to my shows after seeing me making fun of the judges so they will expect this.

"On TV you have to be aware you have a young and adult audience. But any cleaner and it's like a children's show! On stage, I can push further.

"There were jokes about Simon and the panel I couldn't do on TV that I can now do on stage. The new material will be stronger."

Robert will be touring from February to April next year, with tickets going on sale on Friday (29.06.18).

The star - who describes himself on his website as "the only gay, Aspergic, quarter-Welsh comic on the British comedy circuit" - will hope to continue his momentum of reaching the final of this year's 'BGT'.

Robert didn't exactly seem to be holding back much on air, as he suggested David had a lot of contacts on Grindr, and suggested stylish judge Amanda bought her clothes from high street store Primark.

The 'Little Britain' star called him "one of the funniest performers I've ever seen", while Simon couldn't help crack up laughing and described him as "bloody hilarious".
