Patrick Bosco McFadden (born 26 March 1965) is a British politician who has served as Chancellor of the Duchy of Lancaster since July 2024.

McFadden returned to the government following Labour's victory in the 2024 general election, and was appointed Chancellor of the Duchy of Lancaster and Minister for Intergovernmental Relations by Starmer in his ministry.

Prior to becoming an MP, he worked in several advisory roles for Tony Blair, both in opposition and government, and was the Prime Minister's Political Secretary from 2002.

In the 2007 reshuffle he was promoted to Minister of State in the then newly created Department for Business, Enterprise and Regulatory Reform with responsibility for Employment Relations and Postal Affairs.

[11] McFadden retained his post as Shadow Europe Minister when Jeremy Corbyn became Labour leader but was dismissed along with Michael Dugher in January 2016.

John McDonnell said that McFadden's remarks, expressed in a question to the Prime Minister and interpreted as an attack on Corbyn, were an example of him undermining the leader's view.

[14] He supported Owen Smith in the failed attempt to replace Jeremy Corbyn in the 2016 Labour leadership election.

[17] On 9 April 2020, McFadden was appointed as Shadow Economic Secretary to the Treasury by new party leader Keir Starmer.

[20] In 2023, McFadden ranked twenty-fifth in the New Statesman's Left Power List due to his desire to enforce fiscal discipline.

[22] After the general election, McFadden was appointed Chancellor of the Duchy of Lancaster by Keir Starmer to serve in his ministry.
