Britain has had six prime ministers in 10 years. How long did each of them last?

British Prime Minister Keir Starmer resigned on Monday, becoming the sixth person to hold the office in ten years. Starmer served for 717 days before stepping down following poor election results for the Labour Party and growing public dissatisfaction. His departure caps a turbulent decade for the U.K. monarchy, as he joins five predecessors who also left office during this volatile period of British politics, concluding his tenure with a farewell speech at No. 10 Downing Street.
