May’s appointment as home secretary by David Cameron in 2010, when the coalition government was formed, added further layers of complexity to her politics. Cameron joked that he and May were the only two ministers who supported the Tory commitment to reduce net immigration to the ‘tens of thousands’. Yet May also led a crackdown on police ‘stop and search’ powers, which she felt were directed unfairly at young black men, and a crusade to stamp out modern slavery. May was hard to categorise politically.
