The former Watchdog presenter will join Susie and Rachel – who will continue to cover dictionary corner and the numbers respectively – with the pair being branded “formidable women” by Anne.
Nick has since broken his silence on his replacement and wished the former Weakest Link host the best.
“It’ll be very interesting. [Anne’s] a hugely professional presenter so I’m sure it’ll all go swimmingly well,” he told Entertainment Daily.
“I don’t know her to be honest. I’ve never met her. But I think she could teach me quite a lot and I’m not sure the reverse is true. The magic is in the format.”
Countdown airs weekdays on Channel 4 at 2.10pm.
