Christopher Richard Mason was born on 21 April 1980[1][2] in Airedale Hospital in Steeton with Eastburn, Bradford, West Yorkshire.

[1][3] The Yorkshire Post has described Mason's broadcasting style as relatively "informal", and said that that has attracted attention in his television appearances as an occasional host of BBC Breakfast and a political correspondent.

[1] In February 2016, Mason broadcast from outside 10 Downing Street as he unsuccessfully attempted to engage ministers arriving for the cabinet meeting called to discuss David Cameron's renegotiation of the UK's European Union membership.

Mason was praised for his honesty after his comments were shared on social media[1][10][11][12] and translated into French in newspaper Le Parisien.

[1][13] A study of "the Twitter output of 10 seasoned UK political correspondents" found, that Mason was a "prolific" tweeter,[14] and had 66,000 followers between month 1 September and 3 October 2018.

[14] Mason tweeted about a "diverse and humorous range of interests beyond the political scene", including his native Yorkshire and goldfish named after other journalists.

[14] In June 2017, he began presenting the podcast Brexitcast (now known as Newscast) with Adam Fleming and was later joined by Laura Kuenssberg and Katya Adler.

[19] His first show was broadcast from the University of Reading on 18 October with guests Siân Berry, Madeline Grant, David Lammy and Brandon Lewis.

[23] On 13 April 2022, it was announced that Mason would become the new political editor of BBC News and would begin in the role in May, replacing Kuenssberg.
