British Prime Minister Boris Johnson ignited the Brexit debate Sunday, saying Britain will leave the European Union next month despite a parliamentary bill forcing him to seek an extension from Brussels if there is no deal. Johnson made his pledge in a television interview in Manchester as thousands of Conservatives arrived for the start of the last big party conference of the year. (Xinhua/Han Yan)
