[5][6] A supporter of Margaret Thatcher, Pritchard worked as the campaign manager to her successor in Finchley, Hartley Booth, who served in Parliament between 1992 and 1997.

[6][9][10] Pritchard stood as the Conservative candidate in Warley at the 2001 general election, coming second with 22.8% of the vote behind the incumbent Labour MP John Spellar.

[27] He was one of the "Tory Rebels" who oversaw the largest post-war defeat of any Conservative government concerning a European Referendum.

[29] In March 2012, Pritchard had a public confrontation with John Bercow, the Speaker of the House of Commons, who had told him to stand aside in a corridor.

"[30] Pritchard was appointed by Prime Minister David Cameron as a member of the Joint Committee on the National Security Strategy from 2010 to 2015.

[34] He was joined by fellow Eurosceptic MP, Mark Reckless, to draft the so-called 'Reckless-Pritchard amendment' which saw David Cameron's government defeated over the issue.

[36] In November 2013, Pritchard was subject to a series of articles in The Daily Telegraph regarding revelations from undercover investigations that he had offered to use his political contacts to set up business deals with foreign officials and ministers in return for being paid hundreds of thousands of pounds.

[43] Although a eurosceptic, Pritchard supported the official position of his party and campaigned for the United Kingdom to remain in the European Union at the 2016 Brexit referendum.

[47] In January 2017, it was reported that an inquiry had been launched into all-party parliamentary groups amid concerns they were being used to bypass lobbying rules.

[56] In 2022 it was reported Pritchard earned £325 an hour as an advisor to Linden Energy holdings, an organisation which promotes the belief that climate change is inevitable and mitigation is pointless.

Mark Maslin, professor of Earth system science at University College London claims Linden Energy is a classic climate denier.

Prichard was criticised by the Green Party in July 2022 for taking up the role and delaying his entry in the registry of interest by 2 months.

[60] The practice of MPs employing family members has been criticised by some sections of the media on the lines that it promotes nepotism.
