Keir Starmer is to stand down as the MP for Holborn and St Pancras, saying it is the “right time” for him to leave the Commons, according to the Guardian. The move will trigger a byelection in the north London constituency.

Starmer, who resigned as prime minister in July, told the Camden New Journal that he wanted to focus on international affairs and “pass the baton to a successor.” Al Jazeera reported that the departed Labour Party leader now plans to focus on international affairs.

The announcement was made on the same day his successor, Andy Burnham, was due to give his first Commons address as prime minister, the Guardian reported.

The Guardian noted that Burnham, the new prime minister, grew up in the Warrington suburb of Culcheth. Its senior economics correspondent, Richard Partington, who also grew up in Culcheth, has been reporting on what people there are saying about the new PM.

The developments come amid wider political change. The day before, Conservative leader Kemi Badenoch announced a reshuffle, replacing Mel Stride with Andrew Griffith as shadow chancellor and Priti Patel with Tom Tugendhat as shadow foreign secretary, according to the Guardian.

Starmer’s decision to leave the Commons brings an end to his time representing Holborn and St Pancras, a seat he has held while rising to the office of prime minister before his resignation earlier in the summer.
