Who Wants to be a Millionaire will crown its first winner in 14 years on Friday night’s show.
Nobody has won top prize on the show since Charles Ingram hit the jackpot in 2001 and then lost it after being embroiled in a cheating scandal.
ITV announced last month the sixth UK jackpot winner will feature in the latest series of the show meaning on Friday’s episode – the last one left – a contestant will bag the top prize.
The identity of the jackpot winer has not been revealed but they are believed to be a man.
But ITV bosses said viewers will be “blown away” by the performance of the contestant who is “ice cool” under pressure.
Jeremy Clarkson described having the first winner crowned without a studio audience due to lockdown “emotional”.
The former Top Gear host, 60, said: “I’m thrilled and delighted we’ve found someone who seems to know just about everything. I can’t wait for the viewers to see it and I want to watch it back too.
“I was just in awe of this contestant and think they are probably the best the show has ever had in its 22-year history. It was a joy to sit and watch it unfold.”
Despite the identity of the lucky quiz fanatic being kept under wraps by bosses on the show, Clarkson has revealed the moment he knew it was all about to change.
The 60-year-old host claimed that he was sat in front of an “encyclopedia” who tried their luck with several questions.
Jeremy said: “It was like having the Encyclopaedia Britannica sitting opposite me.
“They simply knew the answer. It was just one of those lucky things.”
The former Top Gear host added: “Like the first million-pound winner Judith Keppel, she knew about Eleanor of Aquitaine.
“She’d just happened to have been to that part of France a year before and therefore knew the answer. And this contestant had a couple of those moments. But it’s genuinely staggering to look at someone who has a normal-sized head and then within that head, they have every single fact known to man.“
