I also recently spent the night in an ambulance outside A&E - along with 14 other ambulances in the same situation.
There were not enough beds, trolleys, doctors or nurses to process the arrivals.
Our local A&E is only nurse-led overnight - so everything has been shifted to the larger hospital 40 miles away, which obviously cannot cope.
The doctor I saw said that part of the problem is the number of staff who left to return home to their native countries after Brexit got "done". They cannot recruit nor train fast enough to replace them. It's not all down to Brexit - the Pandemic has also taken its toll, and contrary to what people seem to think, is still doing so.
But years of both government interference and neglect of the obvious mounting problems... the "do more with less" approach, has also had an effect.
Most certainly, not being able to see a GP (for many) has also contributed to the problem.
My partner had a fall recently - head first into the shower, trapped there with his ribcage crushed against the hard edge of the shower tray. We waited 5 hours for an ambulance, during which time he was unable to move and in a pretty bad way when the crew finally arrived. But he was lucky, just two broken ribs and some swelling of the abdomen and an inability to stand for about two weeks afterwards.
I don't believe the government cares one jot about our individual experiences, and its leader is focused on his own survival, so I don't expect the situation will improve any time soon.
