Former British Prime Minister Keir Starmer has announced his decision to step down as a Member of Parliament for Holborn and St Pancras. The announcement was made on Tuesday, marking the end of his parliamentary career. Starmer, who was elected in May 2015, became leader of the Labour Party in 2020 and led the party to a significant electoral victory in 2024. His departure from parliament comes as he shifts focus to international affairs. The move has triggered a byelection, which will test the stability of Andy Burnham's Labour government. Starmer described his decision as “the right time” to leave office, signaling a new phase in his political journey.
