A by-election to fill the parliamentary seat vacated by Keir Starmer in the Holborn and St Pancras constituency is anticipated to occur on October 8. The move to trigger the election was initiated by the Labour Party through a writ, according to two party officials. Starmer, who previously held the seat with a significant majority, announced his resignation from the House of Commons last week, citing a desire to dedicate more time to international affairs. The upcoming election is expected to be a closely contested race, primarily between the incumbent Labour Party and the Green Party, which is fielding candidates including its leader Zack Polanski and councilor Hamza Chowdhury. The Green Party is scheduled to announce its candidate on September 11, just days after its annual conference. Labour is set to choose its candidate on Wednesday.
