London | Britain’s seventh prime minister in a decade, Andy Burnham, has declared he will be a “circuit breaker” and “bring back hope” for a dispirited and divided nation, but financial markets have handed him an early reality check with borrowing costs surging.After meeting King Charles for the traditional “kissing hands” ceremony meant to symbolise the transfer of power, Burnham spoke in Downing Street to the nation for the first time as PM. In another symbolic break, he dispensed with the lectern usually used by prime ministers coming and going, delivering his remarks without notes.
