LONDON (AP) — Boris Johnson is set to form a "cabinet for modern Britain" as he prepares to become prime minister following his victory in an election to lead the governing Conservatives.

The incoming leader has just over three months to make good on his promise to lead the U.K. out of the European Union by Oct. 31.

Johnson easily defeated Conservative rival Jeremy Hunt, winning two-thirds of the votes of about 160,000 party members across the U.K. He becomes prime minister once Queen Elizabeth II formally asks him to form a government.

He will replace Theresa May, who announced her resignation last month after Parliament repeatedly rejected the withdrawal agreement she struck with the 28-nation bloc.
