(AP Photo/Gerald Penny, File) (Newser) – Margaret Thatcher was the first, but she'll no longer be the only female prime minister the UK has ever had. Michael Gove has been eliminated from the ballot to become the next Conservative Party leader, leaving Theresa May and Andrea Leadsom as the final two candidates. The winner will become the UK's next prime minister, the BBC reports. Home Affairs Secretary May (a Remain supporter) led the most recent round of voting Thursday with 199 votes, followed by Energy Minister Leadsom (a Brexit supporter) with 84 and Gove with 46. Conservative MPs will decide on a winner, who will take over the job from David Cameron on Sept. 9, the Washington Post reports.
