Simon Cowell’s firm Syco has threatened legal action against a brand new show that it claims has copied The X Factor’s Six Chair Challenge.
Cowell's talent contest sees judges whittle down contestants in their category by placing their favourites in one of six chairs.
Once all chairs are taken, hopefuls only progress if their judge chooses to replace an act that's already been seated.
Now a new singing competition has come along that Syco alleges has ripped off its format.
In ‘The Final Four’, from Israeli company Armoza Formats, a panel of judges name four singers as the finalists at the very start.
They sit on four seats in the studio - but in every episode, they must defend their spots from new challengers.
Hopefuls must first audition and get unanimous approval from the judges.
If they do, they compete in a sing-off with one of the finalists, with viewers voting on who wins.
The show is yet to be sold to a broadcaster, but it seems Cowell isn't taking any chances.
According to Broadcastnow.co.uk, Syco lawyers have sent a letter to Armoza demanding that it ditches The Final Four.
They're apparently specifically concerned about the use of chairs to denote who will progress through the competition.
This is the second time this year that Syco has moved to defend the Six Chair Challenge.
In January it reportedly issued a warning to The Voice over a new twist to its Battle Rounds.
