In May 1971, a group of Irish feminists staged a protest to legalise contraception.

They travelled from the Republic of Ireland by train over the border to Belfast in Northern Ireland, where it was legal.

There they bought whatever contraceptives they could get over the counter.

When challenged by border guards on their return to Dublin, they refused to hand over their contraband and were cheered by crowds.

Nell McCafferty led the protest and spoke to Witness about the struggle to win the right to family planning in Ireland.
