Theresa May will become Britain's new prime minister today
On Wednesday, British Prime Minister David Cameron will tender his resignation to Queen Elizabeth II after a final round of sparring with the House of Commons, paving the way for Home Secretary Theresa May to take over by Wednesday evening. May, 59, won the race for leadership of the Conservative Party without a vote, after her final rival, Andrea Leadsom, bowed out on Monday. She will be Britain's second female prime minister, after Margaret Thatcher, also a Tory. Cameron has been prime minister since 2010, and he did not seem too despondent about giving up power.
Cameron, who announced his intention to step down after Britain voted to leave the European Union last month, says he will remain a member of Parliament. May, who's been home secretary since 2010 and was in Parliament for 13 years before that, also opposed Brexit, but not very vocally. She is considered a pragmatic moderate in her party, more like Germany's Angela Merkel than Thatcher.
