This is a wicked bit of legislation it will effect the poorer sections of our society the goverment employee and mps will retire on a pension at nearer 60 they can afford to wait for the old age one, but the worker that has not been able to, or his company has gone bust or the company pension fund has collapsed and so on will suffer, I thought labour was a for the worker it for the haves and sod the have nots, blair should be charged with treason
