Sir Charles Ashley Rupert Walker KBE (born 11 September 1967) is a British politician who served as chair of the House of Commons Procedure Committee from 2012 to 2019.

Walker was appointed an Officer of the Order of the British Empire (OBE) in the 2015 New Year Honours for political service, and was appointed a Knight Commander of the Order of the British Empire (KBE) in Theresa May's resignation honours on 10 September 2019, "for political and public service".

[14] His championship of the pay rise and membership of the committee led to him being described by The Daily Telegraph as being in with an outside chance of becoming speaker when John Bercow stood down.

Walker said he had written a report on the subject "years ago" but although he had talked to William Hague and Michael Gove that week, neither had told him their objectives.

[17] Walker was appointed an Officer of the Order of the British Empire (OBE) in the 2015 New Year Honours for political service,[18][19] and was appointed a Knight Commander of the Order of the British Empire (KBE) in Theresa May's resignation honours on 10 September 2019, "for political and public service".

[20] In May 2019, Walker and Cheryl Gillan became acting chairs of the 1922 Committee after Graham Brady resigned to consider standing in the leadership contest to succeed Theresa May as Conservative leader.

[22] Regarding the second tier regulations in November, Walker said "As we drift further into an authoritarian coercive state, the only legal mechanism left open to me is to vote against that legislation.

"[23] In November 2020, Walker called police officers a "disgrace" for enforcing government laws surrounding COVID-19 by arresting a 72-year-old woman who was "peacefully protesting" and who was charged under the Coronavirus Act.

[24] At the time, Walker called for the Constitution of the United Kingdom to be codified into a single written document (it is currently uncodified) to prevent further curbs on civil liberties.

On 1 February 2022, Walker announced he would be standing down at the 2024 general election, saying there had been "a lot of grief and pain" in the country which had meant politics had become a "pretty toxic environment".

[34] During the government crisis on 19 October 2022, Walker called the Truss ministry "a shambles and a disgrace... utterly appalling", commenting of its supporters that he had "had enough of talentless people" for whom "it’s in their own personal interest to achieve a ministerial position".
