Every year, large numbers of abortion seekers from Northern Ireland and the Republic travel to clinics on the British mainland to seek a safe and legal abortion denied them on their own turf.

Ireland’s Hidden Diaspora: The Abortion Trail and the Making of a London-Irish Underground, 1980-2000 unmasks the hidden story of London-Irish women who supported abortion seekers before, during and after their lonely and often frightening journey across the Irish Sea.
