Campaigners carried the names in boxes and crossed Westminster bridge with balloons and banners.
They were responding to a demonstration by Amnesty International, supported by actors in the Derry Girls TV series, calling on Northern Ireland to decriminalise abortion.
Pro-choice campaigners took a petition to the Northern Ireland office signed by 62,000 people, asking for abortion law to be brought in-line with the rest of the UK.
Terminations are currently a criminal offence in Northern Ireland unless it is done to save the mother, physically or mentally.
Amnesty say the laws are “dangerous and degrading”.
Campaigners travelled with 28 suitcases to represent the 28 women who travel from Northern Ireland every week to get an abortion where it is legal.
“And secondly we wanted to have the Northern Irish voice heard and we wanted to have the 100,000 lives recognised. It’s all well and good talking about women travelling but what we like to do is hold both the woman and the unborn together and say that both of those lives truly matter.”
Continuing, she said: “two-thirds of women and also 70% of 18-34 year-olds want these decisions made around abortion law to be made by our own elected politicians and not at Westminster so we feel that Amnesty are actually out step with women in Northern Ireland”.
The 100,000 figure (of those estimated to be alive because Northern Ireland’s abortion law is more limited) is calculated using the abortion rate in England, Scotland and Wales as well as using the number of women who have travelled out of Northern Ireland to do so and estimating the proportion of those people who would still be alive in 2019.
Conservative MP Fiona Bruce said: “Abortion pressure groups are trying to undermine devolution and impose change to abortion law from Northern Ireland. This is bad for devolution everywhere and contrary to Government policy.
These extreme proposals are out of touch with the will of the Northern Irish people, and in particular women. It is clear that a strong majority of Northern Irish women reject interference from Westminster and believe that this is a decision for Northern Ireland.
“I urge the Government to listen to the majority of women in Northern Ireland and reject any pressure to impose abortion on Northern Ireland.”
Pro-life campaigners walk to Westminster.
