Lizzi Collinge was elected Labour MP for Morecambe and Lunesdale on 4 July 2024 with a majority of 5,815 (12.1 percent), defeating Conservative David Morris who had held the seat since 2010. She had contested the same seat in 2019 and lost. The persistence paid off. She now represents a constituency that contains two nuclear power stations at Heysham, the coastal town of Morecambe, Carnforth, Sedbergh and the surrounding rural Lune Valley. She lives in Heysham.

Born Elizabeth Rachel Collinge in Lancashire, she moved to rural Cumbria as a child and spent a period in New Zealand before settling in the Morecambe and Lunesdale area in 2005. She studied as a mature student at the University of Central Lancashire, graduating in 2012 with a first class BA in Politics and Spanish. A mature student achieving a first from UCLan is a different educational trajectory from the Oxford and LSE backgrounds that dominate the Parliamentary Labour Party. It means she entered higher education later than most and came to politics through study rather than through the graduate recruitment pipeline that produces many Westminster careers.

She served on Lancashire County Council from 2016 to 2025, representing Lancaster East ward. Nine years on a county council is genuine executive-level local government experience. Lancashire County Council serves 1.2 million residents and manages budgets under severe real-terms pressure. She was unpaid in the council role from 30 August 2024, maintaining a dual mandate briefly before resigning.

Since entering Parliament she has been appointed to the Energy Security and Net Zero Committee (from late 2025) and has served on bill committees. She has voted in more than 400 divisions with two rebellions. Both rebellions came on the same day, 1 July 2025, on the Universal Credit and Personal Independence Payment Bill. On one division she voted against the government alongside 48 other Labour MPs. On another she voted with 41 other Labour rebels against a majority of 325 Labour MPs. A Labour MP in a marginal seat rebelling on welfare reform is a vote that carries political risk and suggests conviction.

Her nuclear energy position is directly constituency-relevant. Heysham's two nuclear power stations are major local employers and a dominant feature of the constituency's economy and landscape. She has publicly supported nuclear power as part of Britain's long-term decarbonisation strategy.

She is a guest speaker for Humanist UK, having spoken at their 2024 convention, which is a distinctive affiliation for an MP.

Collinge's strengths include nine years of county council experience, a first class degree achieved as a mature student, a 12.1 percent majority gained on her second attempt at the constituency, the Energy Security and Net Zero Committee placement relevant to Heysham's nuclear stations, willingness to rebel on welfare reform, and genuine local roots (resident since 2005). Her weaknesses include limited national visibility, no ministerial office, and a policy profile still being built. The two welfare rebellions and the nuclear energy position suggest she is prepared to take positions rather than drift through her first term. That is a stronger indicator of trajectory than most first-term records show.
