Depends how you define ‘rude’.
IDS was behind the raising of the state pension age for women, causing financial hardship for millions of 50’s born women. He refused to engage with women about their plight.
This from Baroness Ros Altman, who has fought tirelessly for WASPI women:
“As Pensions Minister, I kept trying to find a way to alleviate the unfairness of these short-notice changes. Unfortunately, there was no sympathy for these women. Iain Duncan Smith, as Secretary of State, refused to engage with the 1950s women adversely affected and I was instructed not to speak to them. I was told the women would go away sooner or later.”
