Means testing a winter fuel payment so it’s not being used to put down deposits on next years cruise isn’t exactly “pitting workers against pensioners” is it? But then the Morningstar is half ill-researched waffle, and half conspiracy theory nonsense.
The rise in the state pension this year from the triple lock is several times higher than the winter fuel payments people would be missing - this is even after setting aside the fact that means tested pensioners can still get access to both.
This whole situation reeks of the unions flexing their muscles to try to set a precedent early where they can sway policy. It's a storm in a teacup if you look at the numbers involved.
