A member of Stormont's health committee has asked if the Belfast Health Trust should be placed on "special measures" considering the delays and costs surrounding Belfast's new maternity hospital.
Senior trust executives and Department of Health officials were summoned to the committee following further revelations about the facility, which is almost a decade behind schedule.
It emerged that in the worst-case scenario of fixing the problems there could be a further delay of up to four years with an additional cost of up to £9m.
A potentially dangerous bacteria was first discovered in the water systems at the hospital in 2022 and means there is no date yet for its opening.
