LONDON, United Kingdom (AFP)—Andy Burnham will Monday become Britain’s sixth prime minister to move into Downing Street since 2016, with an in-tray overflowing with challenges and little time to make his mark.

The new leader takes over from the unpopular Keir Starmer just two years after the outgoing prime minister led Labour to power in a landslide election victory after 14 years of Conservative rule.

After being asked by King Charles III to form the next government, Burnham, 56, is due to make his first speech Monday outside 10 Downing Street shortly after Starmer has said his farewells.
