(Reuters) – Andy Burnham became Britain’s seventh prime minister in a decade on Monday, pledging to reshape its politics to deliver a new economic model and revive a nation “fed up” with ​a revolving door of leaders.

In front of dozens of supporters outside his new office and residence at 10 Downing Street, Burnham said politicians had failed to bring the stability needed to raise ‌living standards, something he said he would change, with both immediate measures and a longer-term plan to be drawn up later this year.

Speaking without notes, Burnham delivered a domestic-focused speech aimed at offering hope to a nation that has, like many European countries, struggled for years with soaring prices and anaemic economic growth. He did not touch on foreign affairs.
