After Britain's opposition Labour party trounced the ruling Conservatives in a host of mayoral races and local elections, Labour leader Sir Keir Starmer urges Prime Minister Rishi Sunak to call a general election "as soon as possible". Speaking after Labour's Richard Parker unexpectedly beat Conservative incumbent Andy Street to become Mayor of the West Midlands in another hammer blow for Sunak, Starmer says the election results show "the country wants change".
