The change to women being paid the state pension at 65 instead of 60 was originally laid out in the 1995 Pensions Act.
It was originally due to be phased in over 10 years from 2010 for women born between 1950 and 1955.
But the 2011 Pensions Act then accelerated the process and left women like Angela waiting a further five years to receive payments.
Angela initially approached her local MP Natascha Engel, who put her in touch with other women in the same position.
She then arranged a meeting for those affected in the Portland Hotel in Chesterfield, which became the North East Derbyshire branch of Waspi, and eventually travelled to London to lobby MPs on the issue.
Angela, who is now the national chair of Waspi, said the government of the time failed to communicate the changes laid out in the 2011 act.
“Apparently there were leaflets about it,” she said. “But they were mainly in Benefits Offices and of course having never been unemployed I didn’t frequent Benefits Offices.”
In addition to the leaflets, the government’s website points out television adverts informing people of the changes were broadcast in 2008 and there had been a public consultation two years earlier in 2006, along with a national debate., external
