Luciana Clare Berger (; born 13 May 1981) is a British Liberal Democrat politician who was the Member of Parliament (MP) for Liverpool Wavertree from 2010 to 2019.
She resigned from the Labour Party in 2019 and co-founded The Independent Group.
She later joined the Liberal Democrats and stood unsuccessfully for Finchley and Golders Green in 2019.
As a member of the Opposition Shadow Cabinet, she was Shadow Minister for Public Health from 2013 to 2015, and then Shadow Minister for Mental Health from 2015 to 2016.Born in London, Berger attained degrees at the University of Birmingham and Birkbeck, University of London.
She served as a National Executive Committee member of the National Union of Students, but resigned to protest against what she considered the committee's apathy towards antisemitism.
Berger also joined Labour and served as Director of Labour Friends of Israel.
Appointed Labour candidate for Liverpool Wavertree—her selection attracted criticism for resulting from a centrally-imposed all-women shortlist—she was then elected an MP in the 2010 general election.
As an MP, Berger joined the Shadow Cabinet under Ed Miliband's Labour leadership.
She campaigned against dangerous dogs and their owners, as well as food poverty, and raised the issue of loopholes allowing companies to avoid their health and safety responsibilities.
She was re-elected in the 2015 and 2017 general elections.
Berger was critical of Jeremy Corbyn, who was elected Labour leader in 2015, and resigned from the Shadow Cabinet in 2016.
In February 2019, members of her local party briefly proposed motions of no confidence in her for "continually" criticising Corbyn.
Later that month, she joined other former Labour and Conservative MPs in forming Change UK, but left this group in June 2019 to sit as an Independent MP, before joining the Liberal Democrats in September 2019.
