Irishman Dave McBryan was crowned 2020 Mastermind winner last night.
The 46-year-old, who lives in Edinburgh, Scotland with his wife Lindsay, won the final episode of the current series on BBC Two.
Speaking on RTÉ's Morning Ireland, Mr McBryan said the competition was a "pretty nerve-wracking affair" and he thought he had thrown it away, after making a few silly mistakes during the final.
He said that although he had been one of the favourites to win the title, there was plenty of talent competing against him.
There were 96 contestants in the series. The final was recorded in October 2019 and it was aired last night.
Originally from Dublin, Mr McBryan writes pub quizzes for a living and started competing about seven years ago.

He said that while Mastermind is one of the most prestigious television quizzes, he would not regard it as pinnacle because there is a "whole competitive quiz circuit with a much higher standard" and there are people competing in them who are much better than him.
He is currently second in the Irish rankings and is a member of the Irish National Quiz Team.
This is the second time Mr McBryan has won a major TV quiz, in 2014 he won 'Fifteen to One' on Channel 4.
Mr McBryan is the second recent winner of a prestigious TV quiz title.
Last month, PhD student from Lucan, Conor McMeel, and his teammates from Imperial College London took home the top prize in the BBC's long-running quiz show University Challenge.
