Marie Stopes Service Ability

Marie Stopes UK Managing Director, Paul McPartlan said:

“We’d like to reassure people that we are not suspending any services. January and February are always the busiest times of year for all abortion services and we are currently managing high demand by referring private clients to other providers to ensure they can be seen as soon as possible.

"This is a temporary measure. We believe getting women access to services quickly is the right thing to do when our wait times are high. We'll always support Irish women however we can in Belfast, in England and through our helpline 24 hours a day so they can be seen as quickly as possible.

"If women have any questions they can call us from Northern Ireland on 0345 300 3737, and from the Republic of Ireland (Freephone) on 1 800 200 374.
