LONDON (AP) — It took Andy Burnham a long time to get to the top. He won’t have much time to prove he’s up to the job.

A decade ago, Burnham abandoned a 20-year climb up the Labour Party ladder in London to head north and run for mayor of Greater Manchester. A month ago, he returned to Parliament by winning a risky special election. On Monday, he will become Britain’s 59th prime minister.
