LONDON. 11th July, 2016 (WAM)–Home Secretary Theresa May will succeed David Cameron as U.K. prime minister on Wednesday after her only challenger for the role dropped out, giving her the task of steering the country out of the European Union.

Cameron said he will visit Queen Elizabeth II to resign after his last question-and-answer session in the House of Commons on Wednesday. The monarch will then invite May, 59, as leader of the party with a majority in the House of Commons, to form a government.

“We will have a new prime minister by Wednesday evening,” Cameron said in a brief statement outside his official residence in central London.
