Inclusion Ireland will announce it is joining Together for Yes, the national civil society campaign to remove the Eighth Amendment, as one of its platform members to support a Yes vote in the upcoming referendum.
Inclusion Ireland will also launch a new policy paper, highlighting what it says is "the harmful impact of the Eighth Amendment" on people with disabilities.
Speakers at the event will also draw attention to the additional barriers women with disabilities in Ireland face in accessing abortion care, due to the need to travel abroad.
