The five considerable problems with the chancellor's U-turn on winter fuel payments

There are considerable problems with the winter fuel payment U-turn, but perhaps the political argument in favour outweighs them all? First, Rachel Reeves has executed the plan without working out how to pay for it.

Because the hope is this maxi U-turn lances the boil, removes a significant source of pensioners' anger and brings back Labour voters, a price they calculate worth paying, whatever the fiscal cost.
