Keir Starmer has announced his resignation as the Member of Parliament for Holborn and St Pancras, reversing a previous commitment to remain in the role. This move is expected to trigger a by-election in the London constituency.

The decision could present a significant opportunity for the Green Party, as its leader, Zack Polanski, is reportedly considering standing in the upcoming contest. Starmer's resignation adds a new dynamic to the political landscape, potentially shifting the balance in a traditionally Labour-held seat.

Further details regarding the timeline and the specific implications of this by-election are anticipated. The final results of a poll on Starmer's decision are expected to be published in the Morning Mail newsletter.
