A rally to oppose the closure of maternity services at the Causeway Hospital is due to take place in Coleraine in the days before the cut goes ahead.
The Department of Health confirmed its intention earlier this month to move ahead with a Trust recommendation to halt births at the hospital in Coleraine, with expectant mums set to travel to Antrim instead.
The decision, which is due to take effect from July 17, came despite vocal opposition from several politicians and a campaign dedicated to saving services at the Co Derry hospital.
