The hugely popular quiz show - which is fronted by Jeremy Clarkson after he took over from Chris Tarrant for the revival in 2018 - is still a hit with viewers, and bosses want more.

A source said: "This is a reflection of just how much of a triumph the reboot has been, because even the original 'Millionaire' didn't spawn a spin-off show.

"And that was a phenomenon which was on our screens for a staggering 16 years under its former host, Chris Tarrant, before it was eventually axed in 2014.

"So this shows how much ITV believe the contest has captured the imagination of a whole new generation of viewers."

As the name suggests, the spin-off will be based on the 'Fastest Finger First' round, which sees contestants putting answers to a multiple choice question in a certain order.

The winner is whoever gets it right the quickest, and it has been used as an opening round to see who gets to sit in the hot seat to try and win the huge seven-figure prize.

The new show will focus on this round - with some variations - while it's not clear who will be fronting the spin-off.

It's expected the host will be confirmed later in the year once filming gets underway.

Clarkson has delighted viewers and critics at the helm of 'Who Wants To Be A Millionaire', and even his 'Grand Tour' co-star Richard Hammond has begrudgingly admitted he was impressed.

He previously said: "Annoyingly, I thought the big oaf might fall flat on his face.

"I am not going to say I was looking forward to it, but I really did draw up a chair and think, 'This will be good'. Argh! But he is quite good at it."
