Married in 1950, Chris and Betty Birch have been involved in political, trade union, and LGBTQ+ activism for over 60 years. Sharing similar interests, they were both Communist Party Members and involved with organisations such as the Aid to Spanish Youth Committee. After the death of his friend, Mark Ashton, Chris became involved in forming the Mark Ashton Memorial Trust, which was created to raise money for individuals living with HIV. The archive includes the truncheon taken from the police by Mark Ashton, correspondence, personal scrapbooks, press cuttings, and various other papers relating to the couples activism.
