[1] After leaving the Central School, Diuguid did street theatre and worked with the fringe group A Plum Line which rehearsed in the ballroom of an Eaton Square squat (next door to Lord Boothby's home).
[4] The following year, at her instigation, the first women's festival was held at the Action Space (now the Drill Hall) which trailblazed the future of lesbian theatre, such as Susan Griffin's Voices staged by Diuguid.
[7] Diuguid had a strong alliance with Clean Break, a women's theatre company formed by ex-prisoners, directing the plays The Easter Egg (1983) by Chris Tchaikovsky, a prison reformer, and Lin Coghlan's Apache Tears (2000).
Other major productions included Howard Brenton's Sore Throats (1979); Darrah Cloud's The Stick Wife (1991), about the wives of three Ku Klux Klan members; and Request Programme, by Franz Xaver Kroetz (1986) with actress Eileen Nicholas, for which Diuguid won a best director award.
Throughout the 1980s and 1990s, she travelled extensively in Australia, Brazil (as a guest director, at the British Council Theatre Group, with Luiz Päetow), Japan and Israel (where a traumatic personal experience led, 10 years later, to her shortfilm Aftermath).
