Two senior medics involved in NI's cervical screening programme have resigned over their concerns about the service.

Stella McLoughlin from the campaign group Ladies with Letters says what has happened was unforgivable.

The review into cervical screening at the Southern Health Trust was triggered when the diagnoses of three women were investigated.

Fewer than half the 25 to 49-year-old women called for testing are attending appointments.

She is encouraging people to attend their appointments while offering advice and education.

A nurse "may have worked outside of the professional remit", according to hospital documents.

The Southern Health Trust say the review is almost complete, with about 80 women waiting on results being finalised.

A wellbeing board says not enough women in Herts are taking up free NHS cervical screening tests.
