By Monday, Andy Burnham could be walking into Downing Street with the most ambitious regional-growth agenda of any prime minister in a generation. He is set to be confirmed as Labour leader tpmorrow and sworn in as prime minister at the start of next week, in one of the fastest unscheduled handovers of power in modern British politics. Remember, this is a man who was not even an MP a few weeks ago.

Business leaders have not had the time, or the necessary detail, to properly interrogate his promises. What they do know is that growth rhetoric, however persuasive, will not deliver the economic jolt this country needs.
