He wants to move some government operations to Manchester and favours greater “public control” of transport, water and energy.He also backs cuts to business rates for pubs and music venues.Keir Starmer and wife Victoria outside No 10 after announcing his resignation [Toby Shepheard/Reuters]Fiscal pressures remainIf he takes office, Burnham would be the UK’s seventh prime minister in a decade.But fiscal pressures will be a constraint, with the UK economy struggling from the impact of the war in Ukraine and the US-Israel war on Iran.Burnham once said the government should “get beyond this thing of being in hock to the bond markets”, but later said he was misrepresented.His choice of finance minister will be closely watched as a sign of how left-wing his government could be. United States President Donald Trump called Burnham “extremely liberal” and unlikely to open the North Sea to oil and gas drilling.
