By PAN PYLAS LONDON (AP) — Andy Burnham ’s resounding victory on Friday in a special U.K. election sets in motion a chain of events that could lead to the end of the premiership of Keir Starmer, who less than two years ago led the Labour Party back to power after 14 years. Burnham, the former mayor of Greater Manchester, is widely tipped to be the lead candidate to replace Starmer, especially as his victory in the seat of Makerfield in northwest England was so decisive.
