Patients have been waiting up to three days in the corridors of A&E with the hope to be seen by a doctor – but just what is causing this delay?

Journalist Paul Brand brought the reality of NHS struggles to the surface in a documentary which aired on ITV’s Tonight programme on Wednesday.

He spoke to May, a 92-year-old patient who had been waiting for three days to be seen by a doctor and her daughter.

Her daughter said she thought never “in a million years” would her mum have to wait this long in A&E. Another patient, Hugh, was waiting 15 hours to be seen by doctors even as he had water around his lungs and heart.

He said: “They’re doing their best, bless them.”
