Lilian Greenwood has been MP for Nottingham South since 2010 and currently serves as Parliamentary Under-Secretary of State for Local Transport and Government Whip (Lord Commissioner of HM Treasury), holding both roles simultaneously since 16 September 2025. She is one of the most experienced transport specialists in Parliament. Over 15 years she has held the Shadow Rail Minister brief, the Shadow Secretary of State for Transport position, the Transport Select Committee chair, the Future of Roads ministerial portfolio, and now the Local Transport brief. No other serving MP has accumulated comparable depth across transport policy.

Born Lilian Rachel Greenwood on 26 March 1966 in Bolton, Lancashire, she was educated at Canon Slade School and St Catharine's College, Cambridge. Before entering Parliament she worked as a regional official for UNISON, the public services union. Her 2024 majority was 10,294 (31.3 percent), making Nottingham South a safe seat.

Her ministerial career since July 2024 has already involved significant movement. She was appointed Minister for the Future of Roads on 9 July 2024. She was moved to Vice-Chamberlain of HM Household (a government whip position) on 7 September 2025 during the reshuffle triggered by Rayner's resignation. Nine days later, on 16 September 2025, she was appointed Minister for Local Transport while retaining a whip role. The nine-day stint as Vice-Chamberlain suggests the reshuffle was still being finalised when her initial move was announced.

Her career before government was built through opposition transport roles: Shadow Rail Minister from 2011 to 2015, Shadow Secretary of State for Transport from 2015 to 2016, Transport Select Committee Chair from 2017 to 2020, Finance Committee Chair from 2020 to 2021, Opposition Deputy Chief Whip from 2021 to 2023, and Shadow Minister for Arts, Heritage and Civil Society from 2023 to 2024. The detour through culture and the whip's office broadened her portfolio but transport was always the specialism she returned to.

Specific transport achievements in Nottingham include securing £60 million of funding to refurbish Nottingham's main train station, campaigning for the widening of the A453, and supporting extensions to the Nottingham tram network. As Roads Minister she delivered a significant increase in pothole repair funding for 2025/26 and became the first minister to present in person at the National Road Safety Conference in November 2024.

Greenwood's strengths include Cambridge education, 15 years of transport policy specialism across shadow, committee and ministerial roles, specific infrastructure delivery for her constituency, a safe 31.3 percent majority, and the institutional knowledge that comes from chairing a select committee and serving as Deputy Chief Whip. Her weaknesses include a national profile that does not match her seniority (few voters outside Nottingham could name her), a ministerial portfolio that is junior relative to her experience (Under-Secretary rather than Minister of State), and a career that has been defined by one policy area to such an extent that it may limit her advancement beyond transport. At 60, with 15 years of service and a dual ministerial and whip role, she is at the peak of influence she is likely to reach unless a more senior transport role opens.
