This up beat film rightly pitches the mood of a generation of women who are not going to lie down and lose tens of thousands of pounds each because of a cruel, incompetent government which thought it could get away with raising the pension age without telling them.

It is a worthy rebuke to George Osborne, the multi millionaire former Tory chancellor and editor of the Evening Standard who once boasted about the removal of the benefit:

“I’ve found it one of the less controversial things we’ve done and probably saved more money than anything else we’ve done.“

Instead he has left the Department of Work and Pensions with a multi million pound legal bill and that’s only for starters. If the women win it is going to be one of the most costly decisions George Osborne has ever made.
