The mother-of-two, 39, was triaged when she arrived at Queen's Medical Centre in Nottingham on 19 January complaining of a headache and was seen multiple times by nurses, according to reports.

But she is said to have fallen unconscious while waiting for more than seven hours to be seen by a doctor in the accident and emergency unit. She died in intensive care of a brain haemorrhage two days later.

The woman was reportedly found by staff when her name was called to see a doctor and she didn't respond.

Dr Keith Girling, medical director at Nottingham University Hospitals NHS Trust, said: "I offer my sincere condolences to the family at this difficult time.

"An investigation, which will involve the family, will now take place and until this has been concluded, we are unable to comment further."

Lilian Greenwood, the Labour MP for Nottingham South, told LBC, which first reported the story, that the woman's death was "disturbing". The MP welcomed the investigation into what happened.

She also said "her thoughts and condolences are with the family and friends of the mother-of-two".

The case could be escalated to an external independent investigation depending on the outcome of the probe.
