On Friday 1 November 2019, she was selected as the
Labour candidate for
Luton South. She was selected by a panel of four, rather than by the local membership. Hopkins is considered to be on the left of the Labour Party, and joined the
Socialist Campaign Group upon her election to Parliament. She voted for
Brexit in the
2016 EU referendum, making her one of the few known Labour MPs to have done so. Hopkins was appointed
Parliamentary private secretary (PPS) to the
Shadow Women and Equalities Secretary,
Marsha de Cordova, in May 2020. Hopkins resigned from the position to vote against the
Covert Human Intelligence Sources (Criminal Conduct) Bill, rebelling against the Labour whip. She became a PPS once again in May 2021, this time to
Shadow Defence Secretary John Healey. Hopkins was appointed as a Shadow
Cabinet Office Minister in the December 2021 opposition front bench reshuffle. She was appointed Shadow Minister for Veterans and Defence people in July 2022. In November 2023, she resigned from the frontbench to vote for a ceasefire in Gaza. Due to the
2023 review of Westminster constituencies, Hopkins' constituency of Luton South was abolished, and replaced with
Luton South and South Bedfordshire. At the
2024 general election, Hopkins was elected to Parliament as MP for Luton South and South Bedfordshire with 35.4% of the vote and a majority of 6,858. Hopkins is a co-sponsor of
Kim Leadbeater's
Terminally Ill Adults (End of Life) Bill on
assisted suicide. ==Personal life==
