With George Osborne sacked as Chancellor by Theresa May, the fate of the Northern Powerhouse – his pet project – seemed at risk. Enter Andy Burnham, ardent campaigner for the Northern Powerhouse, as the winner of Labour’s Greater Manchester mayor nomination last week. If elected next May, Burnham has vowed to uphold a bold regional agenda including plans to radically transform the housing market. Business welcomes the idea of a Manchester mayor but is concerned about any change to an economic model it sees as already successful. It is encouraging that these first fruits of devolution and a powerhouse premium are beginning to be realized as true sources of economic potential. The Northern Powerhouse is a £300bn economy – it will be hard for the new government to resist its momentum.
