First term (2017–2019) At the
2017 general election, Jones was elected the Member of Parliament for
Bristol North West, overturning a Conservative majority of 4,944 on a 9.2 percent swing. In his
maiden speech, Jones noted that he was the first Darren ever elected to Parliament. Between 2017 and 2020, Jones was a member of the cross-party
Science and Technology Committee and the
European Scrutiny Committee. In 2019, then
Deputy Leader of the Labour Party Tom Watson appointed Jones as the Convenor of the
Future Britain Group, which was established following a number of defections from the
Labour Party in a bid to prevent further defections.
Second term (2019–2024) Jones was re-elected at the
2019 general election, with an increased majority of 5,692 but a decreased vote share of 48.9%. Following
Keir Starmer's
election as Labour leader in April 2020, Jones was appointed
Parliamentary Private Secretary jointly to
Shadow Justice Secretary David Lammy and
Shadow Attorney General Charlie Falconer, and served until his election as Chair of the
House of Commons Business, Energy and Industrial Strategy Committee. Jones built a national profile as Chair of the House of Commons Business, Energy and Industrial Strategy Committee, winning a number of awards and attracting millions of views of his committee hearings on social media. He led on a number of issues including the withholding of redundancy payments from
AstraZeneca workers, the campaign to increase miners' pensions through the Mineworkers Pension Scheme, and the
British Post Office scandal, the right for workers to join a trade union at
Amazon and the dispute related to changes at
Royal Mail. In 2020, he introduced the UK's first
citizens' assembly on
net zero to Parliament. He has also led Parliamentary inquiries into the decarbonisation of heating, electricity and industry, as well as reform of the energy market in the United Kingdom. Jones also sat on the
National Security Strategy Joint Committee and, following the introduction of the
National Security and Investment Act 2021, became responsible as Chair of the
Business, Energy and Industrial Strategy Committee for holding the Government to account for its use of national security powers. He has also served on the
Liaison Committee, the committee that scrutinises the Prime Minister. As a member of that committee, Jones had frequent notable exchanges with then-Prime Minister
Boris Johnson, including during the final days prior to Johnson announcing his resignation in July 2022 when Jones informed him that his cabinet was waiting for him in
10 Downing Street to tell him to resign. Jones was the founder and chair of the Interparliamentary Forum on Emerging Technologies, a global network of legislators interested in emerging technology regulation, and in 2021 was appointed to the
Online Safety Bill pre-legislative scrutiny committee. In 2021, he passed the Forensic Science Regulator Act 2021, having been successful in the ballot for a
Private Members Bill, giving the
forensic science regulator statutory powers to ensure service quality standards from the privatised forensic science companies working with the
police. 2022 In 2022, Jones was appointed as a member of the
UK-EU Parliamentary Partnership Assembly. In the
2023 British shadow cabinet reshuffle, he joined the shadow cabinet as
Shadow Chief Secretary to the Treasury. He has been described as one of the Labour Party's strongest communicators and became one of the most recognisable faces of the shadow cabinet during the 2024 general election campaign.
Third term (2024–) At the
2024 general election, Jones was again re-elected, with an increased vote share of 49.6% and an increased majority of 15,669; representing the largest majority ever recorded in
Bristol North West. Jones was appointed
Chief Secretary to the Treasury and attends Cabinet. As deputy to the Chancellor, he is responsible for public spending, delivering the government's ten year national infrastructure strategy and leading for HM Treasury on the digital transformation of public services. Since April 2025, he has also been responsible for the
National Infrastructure and Service Transformation Authority (NISTA). Jones apologised for comments he made after the
March 2025 United Kingdom spring statement, where he used the example of
pocket money when talking about cuts to
Personal Independence Payments for disabled people. The Chancellor of the Exchequer
Rachel Reeves had said it was "not the right analogy" when asked about the comment in an interview. On the BBC's
Question Time on 12 June 2025, Jones said of
English Channel migrant crossings "And when you see that the majority of the people in these boats are children, babies and women… you have got to take note". Jones rejected fellow panellist
Zia Yusuf's statement that 90% of cross-Channel migrants were men. In 2024, 76% of migrants were adult men, while in the first three months of 2025 it was 81% adult men, with children being four-fifths male. Conservative leader
Kemi Badenoch called for Jones to retract his statement and apologise. The following day, Jones said that the majority of migrants were men, and that his statement about women and children being the majority referred to one visit he had made to
Border Security Command. In a cabinet reshuffle on 1 September 2025, Jones was appointed as
Chief Secretary to the Prime Minister and was succeeded by
James Murray as Chief Secretary to the Treasury. He was also appointed as
Chancellor of the Duchy of Lancaster on 5 September, after
Pat McFadden succeeded
Liz Kendall as
Secretary of State for Work and Pensions. == Political positions ==
