Simon Cowell is reportedly planning to launch a new National Lottery-style gameshow.

According to the Daily Star Sunday, the talent show judge wants to produce an interactive prize draw show, giving cash prizes to viewers who buy scratchcards. The programme will also include performances from Cowell's acts.

A source said: "Simon's really excited about bringing a new game show to our screens but everyone is sworn to secrecy. He hopes it will be good enough to grab the nation's attention and be as big as The X Factor."

Speaking last week, Cowell said: "I have to be very careful about what I say in advance because, the minute you announce something, somebody else comes along and pinches it.

"And I don't like to hype these things - if they work, they work. I want the public to discover them for themselves."

A Camelot spokeswoman refused to confirm whether or not the National Lottery operator has held talks with Cowell.
