Gordon Brown said he'd abolished the economic cycle. Whatever happened to him? The cycle drags politicians and their plans up and down. It will also decide the hardness of Brexit. Tough negotiations abroad and tougher economic times at home will be a hard seesaw to ride.

These figures (and those on inequality out today) show Brexit should only be the cutting edge of government policy, not the whole machine. The economy needs a detailed industrial strategy, ambitious housing and infrastructure investment and real measures to help the JAMs. Dramatic steps need to be taken soon.

So the biggest domestic event this spring, won't be triggering Article 50. It will be the budget. The most important budget since Geoffrey Howe's in the early 1980s. 

Budgets are the government's main chance to influence the economic cycle. The budgets of the next two years will make or break Brexit.
