Polanski to contest Starmer's former Holborn and St Pancras seat in by-election
Green Party leader Zack Polanski will stand in the Holborn and St Pancras by-election to fill Keir Starmer's seat, citing strong ties to the community and hoping to attract left-leaning voters as Labour faces ongoing scrutiny; Starmer's resignation triggers the race and the Greens have recently gained ground at the national level, despite Polanski's own popularity being tested by criticism over a police arrest incident.
