When Theresa May became Britain’s 54th prime minister in mid-July, she took the helm of a Conservative Party in turmoil, reeling from a shock result in the Brexit referendum on membership in the European Union. The bruising campaign exposed deep fault lines within the Conservative Party, which has long divided on the issue of Europe. May has now been in office for 100 days, and has made significant breaks with the agenda of her predecessor, David Cameron. However, the disarray in the Labour Party, which has spent much of the last three months embroiled in its own leadership election, has meant May has faced little opposition thus far.
