Hard to understand what this could possibly mean.
They don’t need the money to reassure the markets about debt? Seems highly unlikely.
Or that they’ll borrow more, or print? Suicidal.
Or that they’ll cut spending massively? Er, no, not possible, backbenchers and all.
Or that they’ll tax some people huge sums on wealth but no-one on income? That would be madness and would lead to capital flight and catastrophe on longer-term bond yields.
I think this is more Labour spin.
