Abortion Rights hosted a 50-strong public meeting in London last Saturday with speakers from the north and south of Ireland.
This was followed by the campaign’s annual general meeting.
The meeting committed to set up local groups to combat the rise of militant anti-abortion pickets outside clinics.
Maria Caddel, a Belfast activist working with Alliance for Choice, said thousands of women have travelled to England to access a legal abortion.
Up to 70,000 women have come to England since 1967 when abortion was legalised everywhere in the UK apart from Northern Ireland.
Barrister Natalie McDonnell and activist Stephanie Lord spoke from Dublin. They talked about the wave of protests sparked when Savita Halappanavar died after being denied an abortion in a Galway hospital.
They said the protests have galvanised the campaign for a change in the law in Ireland.
