Thank you for replying. I must admit they contradict some of what I found, so I'll maybe dig a little further to find out the context.
I'm afraid the WASPI campaign gets up my nose because the people in charge of it wouldn't accept a means-tested compromise. They're all professional, well paid women themselves and don't actually need the extra money and gave up the chance to campaign for those who really need it. (But that's another issue)
I don't have any sympathy for the women who didn't know the SPA had been increased in 1995. If they care so little to find out about something which affects them personally, I really wonder how much they are aware of changes to benefits, etc which don't affect them. The 2011 changes were different. Labour had introduced the idea of an extension in 2007(?) and the coalition brought the extension forward. I must admit I don't remember it's being Clegg's idea, although I do remember him being involved in the delay to the implementation, when it was realised how unfair it would be to a certain small group of men and women.
My big bugbear is that the public generally couldn't have cared less and didn't campaign to overturn all the other changes to the benefit system (such as the minimum number of worked hours needed for Universal Credit), which could have mitigated the hardship for those most affected. The WASPI organisers didn't care because they weren't in the group which needed most help. They were too concerned about trying to get their £thousands lump sum.
BTW I'm not defending Clegg. I was appalled by the LDs in coalition and for the first (and until now only) time in my life voted Labour in 2015. I just don't like people being accused of things, unless I know the background. There's far too much of it in politics.
