Labour's Shadow Chancellor John McDonnell has said if his party is elected at the next election it will not abolish the sugar tax announced in yesterday's Budget.
Speaking on Good Morning Britain, Mr McDonnell said Labour supported the reasoning behind the tax but did not think it would work unless it was part of a wide health strategy designed to tackle obesity.
We welcome the sugar tax but the problem is it's not part of an overall strategy to tackle obesity and whilst George Osborne is introducing the sugar tax, he's cutting £200m from the public health budget.
In principle we support it but we have to see the detail as it rolls out.
The lower growth forecast for the economy means the Chancellor will have to raise taxes or make drastic cuts, the economic think-tank said.
The Budget seems to be a return to 'nudge, nudge' politics which looks at behaviour, the cost of dealing with it, and makes a calculation.
Around 20 Tory backbenchers wrote to the Chancellor, even before the Budget was delivered, to outline their concerns about the measure.
