UK Prime Minister Rishi Sunak has announced his resignation following a significant defeat in the general election to the Labour Party, led by Sir Keir Starmer. Sunak, who retained his seat in Richmond and Northallerton, conceded defeat and apologized to the British public, acknowledging their anger and disappointment. He described the election result as a 'sobering verdict' and stated, 'I am sorry.' Sunak will step down as Conservative Party leader once arrangements for his successor are in place, but not immediately. He will visit the King to offer his resignation as Prime Minister, paving the way for Starmer to become the new Prime Minister.
