Earlier this week, Paxman announced his departure from the series after 28 years at its helm. His final series will air from 29 August through to Summer 2023.

Said Paxman: “I’ve had a blast hosting this wonderful series for nearly 29 years. I’ve been lucky enough to work with an amazing team and to meet some of the swottier brains in the country. It gives me hope for the future.”

Rajan has been BBC News’ Media Editor since December 2016 but he will step down later in the year. He will, however, continue his presenting role on the BBC Radio 4 Today programme.

Commenting on his appointment, the broadcast journalist said: “Being asked to host my favourite TV programme is dream-come-true territory. I have watched University Challenge obsessively for years, addicted to its high standards, glorious title music, and inspirational contestants.

“It’s the best possible antidote to cynicism about young people, allowing millions of us to test our wits against the best minds of a new generation, and annoy and impress our families by barking answers from the sofa.

"I am very conscious that in the late, great Bamber, and that giant of British culture, Jeremy, I have vast shoes to fill. With his immense intellect, authority, and respect from students and viewers alike, Jeremy hands over a format, and show, as strong as ever.

"I won’t stop thinking today about my late, beloved Dad, whose devotion to Education brought him to England, whose love of Knowledge I imbibed as a kid, and whose belief in the noble challenge of university so shaped my life.

“I’ll devote my first Starter for 10 to him - and to the millions of quiz fiends who, like me, love those rare occasions when they know the answer before the students do.”

Now in its 60^th year, University Challenge is Britain’s longest-running quiz show. To mark the occasion, a special documentary will air on BBC Two on 29 August at 9.00pm.
