I paid in tax and NI since I was 16, much of it in service to my country. It was a deal both sides agreed to and it should not be broken just because in one year the increase could be better than expected.
The UK already has one of the lowest OAP rates in Europe and our incomes and outgoings are fixed - no overtime for us poor sods. There have been many times when inflation has been higher than the pension increase and governments of all colours have been happy with that. Now it looks to be temporarily going the other way the *******s are bitching and moaning.
