For the second time in little more than two years, this week a new UK Prime Minister stood in front of 10 Downing Street and promised “change”. After Sir Keir Starmer’s premiership was ultimately torpedoed by a perception among a sufficient portion of the population that change was not happening quickly enough, the country could be forgiven for feeling a little sceptical about the early pledges made by his successor, Andy Burnham, of the introduction of a “circuit breaker” into British politics, of “bringing forward the biggest changes in the last forty years” and of “a new political model and a new economic model”.
