Prime Minister Keir Starmer has defended the decision to reject compensation for women hit by changes to the state pension age, arguing that the taxpayer "simply can't afford the tens of billions of pounds" in payments.
He added that "90% of those impacted knew about the changes that were taking place".
However, during Prime Minister's Questions, Sir Keir was repeatedly pressed on the government's decision, with one MP calling for a vote.
Campaigners say that 3.6 million women born in the 1950s were not properly informed of the rise in state pension age to bring them into line with men.
