The Prime Minister's core message during the campaign was simple: "Get Brexit done." It worked, with the Conservative Party enjoying its widest margin of victory since its win under Margaret Thatcher in 1987. The United Kingdom now appears set to leave the European Union by the end of January. The opposition Labour Party, meanwhile, had a historically poor showing in the polls, while nationalist parties made gains in Scotland and Northern Ireland.
