Anne Robinson has been unveiled as the first female host of Countdown and said she is excited to work with the show's two other "formidable women".
She will join mathematician Rachel Riley and lexicographer Susie Dent on the Channel 4 daytime show.
Robinson, who previously hosted game show The Weakest Link, will replace Nick Hewer after he announced he would be stepping down after nearly 10 years in the hot seat.
Speaking about her new role, she said: "I am beyond thrilled to be joining Countdown. The show is almost as old as I am and just as historic.
"I am particularly excited to be working alongside the show’s two other formidable women."
"Worryingly, Susie and Rachel are not only very smart but younger, prettier and thinner than me.
"Sadly, there’s no time for another facelift so I’ll have make do with this old one.
"Three Clever Girls Do Countdown! Don’t you love the sound of that?
"I am a crossword nut so the Countdown’s conundrums I can make sense of. But the adding up and taking away – I can’t go much further than working out the fee once my agent takes his cut."
Countdown was the first programme to be broadcast on Channel 4 and has been on air since its launch in November 1982, making it one of the longest-running quiz shows in the world.
Robinson appeared in Countdown’s Dictionary Corner for a week in 1987, when the show was hosted by Richard Whiteley.
She said: "I was so in awe of the great Richard Whiteley. I think I only said 'Good afternoon’ and ‘Goodbye’.
"Who thought I’d have the chance to follow in his giant footsteps?"
Countdown is on weekdays at 2.10pm on Channel 4.
