Luciana Berger was also overlooked by constituents in Finchley and Golders Green, who re-elected Conservative candidate Mike Freer.
Berger, who was the Labour MP for Liverpool Wavertree for nine years, stood in the London constituency after joining the Lib Dems earlier this year.
She defected from Labour in February after describing the party as “institutionally anti-Semitic”, joining the newly-formed Change UK. She moved on to the Lib Dems four months later.
The election saw a record 1,124 women stand as candidates, with Barking, Chippenham, Llanelli and Telford all having all-female ballots.
More than half of Labour’s candidates were women (335 of 631), making it the only party with equal, or better-than-equal, representation for women.
According to the BBC, of the SNP’s 59 candidates, 20 were women – about 34%.
Meanwhile, 31% of Lib Dem candidates (188 of 611) and 30% of Conservative candidates (192 of 635) were women.
