The issue of drunks clogging up A&E (or anyone else abusing the service) has gone on too long and needs addressing, but it is hardly a new phenomenon.
My feeling is that the following extracts of reports from a variety of news sources amply demonstrate why six English hospitals have declared major incidents and why it would appear that the NHS emergency services are approaching breaking point.

Three-week wait to see your doctor: Millions of patients are denied a prompt appointment to see their GP
(An inability to get a timely GP appointment can lead to a patient's condition deteriorating and perhaps requiring a hospital admission or a hospital referral. It can also lead to people turning up at A&E for treatment of conditions that are not emergencies.)

111 helpline has fundamental flaw, say critics
..... lay call handlers, who are cheaper, follow a script of questions that leads them to a decision about where to send the caller. Handlers have no clinical experience, the system has to default to the least risky option – which means sending people to A&E or calling an ambulance if there is any doubt.

A&E closures 'affect death rates'
Closing hospital accident and emergency (A&E) departments has knock-on effects that lead to more patient deaths, a US study has shown.
They found that A&E closures had a "ripple effect" that extended out to nearby hospitals. The problem was caused by closure increasing pressure on nearby emergency departments (EDs) that found themselves forced to cope with more admissions.

Cuts forcing English councils to limit social care
Guardian March 2014
Cuts have left 250,000 older people without state care, report says
A quarter of a million older people have lost their state-funded help with carrying out everyday activities such as bathing, dressing and eating in the past four years as council budgets have been slashed.
The number of vulnerable older people receiving "meals on wheels" services dropped by over half, while care services carried out in the home or in day centres were cut by a fifth
(It seems fairly obvious to me that if elderly people are not eating properly and are unable to attend adequately to matters of personal care, then it is much more likely that they will succumb to a variety of illnesses that may well require admission to hospital. The cuts also mean that, even if people are well enough to be discharged from hospital, the lack of rehabilitative/convalescent support means they often have to stay in hospital, thus reducing the number of beds available)
