LONDON (AP) — Boris Johnson is convening his first Cabinet meeting as Britain's prime minister, pledging to break the impasse on issues that flummoxed predecessor Theresa May.

Johnson has less than 100 days to make good on his promise to deliver Brexit by Oct. 31 after what he called "three years of unfounded self-doubt."

The new Cabinet arrived early at Johnson's Downing Street office — a collection of fresh faces after Johnson culled senior members of May's team. The new line-up includes Foreign Secretary Dominic Raab, Treasury chief Sajid Javid and House of Commons leader Jacob Rees-Mogg.

In his first speech as prime minister, Johnson offered a plethora of promises, from more police on the streets to ending a ban on genetically modified crops to faster internet access.
