I did a presentation on this in politics and I think they came to some sort of agreement whereby public sector workers (or maybe anyone whos currently in the pension scheme, not sure) can take advantage of the current rules although any new workers would have to take up the 67 years old pension when it was implemented..
something to that effect, its a load of rubbish if you ask me.
(My presentation was mainly on UNISON so I didn't go into that much detail, but thats what I gathered above
)
