Former prime minister Boris Johnson warned voters in the heavily Jewish seat of Finchley and Golders Green against voting Labour at the general election.

In a video encouraging voters to back the Conservative candidate Alex Deane, Johnson said: “We’ve only got a few days now from the nightmare of what could be a Starmergeddon supermajority.”

Johnson, who defeated Labour and Jeremy Corbyn in 2019 and led the Conservatives to their biggest electoral victory since 1987, warned voters of “ever more wokery, more illegal immigration, and ever higher taxation for you and your family under Sir Keir Starmer.”

An estimated 20 per cent of voters in Finchley and Golders Green are Jewish — the largest proportion in the country.

Boris Johnson resigned as Prime Minister in 2022 after a series of scandals – such as Partygate and his handling of complaints about former Deputy Chief Whip Chris Pincher – rocked his administration and he lost the confidence of ministers and MPs.

In June 2023 he stepped down from Parliament and accused a committee looking at his behaviour during partygate of "witch hunt" against him.

Alex Deane, the Conservative candidate in Finchley and Golders Green, told the JC: “I’m grateful to the former Prime Minister for his support.

“From his leadership in the West’s support for Ukraine to his steadfast commitment to the Jewish community, he gets the big calls right - like who to vote for in Finchley and Golders Green!”

The Conservatives have held Finchley and Golders Green since 2010. Justice Minister Mike Freer who represented the seat is stepping down at the upcoming general election following death threats and an arson attack on his local office.

Labour’s candidate for Finchley and Golders Green is Sarah Sackman, interviewed by the JC here. A poll published by Ipsos last week said the seat would likely go Labour on July 4.
