I’ve seen what the death of major industry did to Britain. Without a good revival plan, Burnham cannot succeed | John Harris

Collieries turned into retail parks, manufacturing in the doldrums. The problem is vast, but at least the PM-in-waiting sees it: and in that there is hope

In the autumn of 2005, Tony Blair gave one of his most unhinged and fascinating speeches as prime minister. “I hear people say we have to stop and debate globalisation,” he said. “You might as well debate whether autumn should follow summer.” He went on: “The character of this changing world is indifferent to tradition. Unforgiving of frailty … It has no custom and practice. It is replete with opportunities, but they only go to those swift to adapt, slow to complain, open, willing and able to change.”

In the hall, his characteristically messianic delivery ensured this argument landed, but anyone listening from one of the UK’s deindustrialised areas must have received it as yet another punch in the face. For decades, change and adaptation were what they had been living through and reeling from – but where were the rewards? Where, indeed, was any real sign of even the beginnings of the 21st-century prosperity Blair seemed to be offering?
