Green Party’s Zack Polanski to Seek UK Parliament Seat Vacated by Keir Starmer

Zack Polanski Announces Candidacy for Holborn and St Pancras

LONDON, Sept 3 (Reuters) - The leader of Britain's left-wing Green Party intends to stand in an election for a seat in parliament vacated by former Labour prime minister Keir Starmer, a local newspaper reported on Thursday.

Polanski’s Campaign and Critique of Labour

Zack Polanski told the Camden New Journal he would be the Green candidate for Holborn and St Pancras, a left-leaning constituency which Starmer held comfortably in 2024 though with a much-reduced vote share.

"Labour stands up for corporations and big money," Polanski posted on X. "I'll stand up for people and our communities."

Previous Election Results and Green Party Prospects

In an election two years ago, an independent candidate who campaigned primarily on opposition to Israel's war in Gaza took nearly 19% of the vote while the Green candidate received over 10%, giving the party hope of taking the seat this time.

Green Party’s Recent Successes and Challenges

Since Polanski became Green leader a year ago the party has had success in taking support from Labour's left, winning a surprise by-election victory in Greater Manchester – where current Prime Minister Andy Burnham was a long-serving mayor – and nationally polling as high as 20%.

But Polanski's personal popularity took a hit after he criticised police officers for the way they arrested a man who allegedly stabbed two Jewish people in north London in April, according to pollsters YouGov.

Current National Polling Landscape

A national YouGov poll on Wednesday put Labour tied with the right-wing populist Reform UK party of anti-Brexit campaigner Nigel Farage on 23% with the opposition Conservatives on 20% and the Greens on 13%.
