And then, of course, there's the EC, who see the NHS as a monopoly that needs breaking up and opening up to (European) competition: but hey, let's just Tory bash, and conveniently ignore the Brown-beloved PFI deals and the increased NHS spend since Labour left office 
But that aside, it's not surprising that GP appointments are at a premium: we have an ever-increasing population in the UK, and that inevitably puts pressure on all services and infrastructure, whether that's social housing or doctors. Add to that what is often a slight lack of commonsense in the general public (if it's not an accident or an emergency, you shouldn't really be at A and E...) and the delights of 111, and it's not surprising that there are people there who oughtn't to be.
I had an accident before Christmas, and was captivated (in a really bad way, I confess) by the lady with back pain who arrived by ambulance who ordered a take-away pizza to be delivered within five minutes of her arrival, and then disappeared outside for a smoke whilst she was waiting for it. On the one hand, clearly no harm, as she wasn't going to be seen for a while - but on the other: calling an ambulance for a bad back that is not so bad you a) fancy food and b) can get up and go for a fag? Sadly, that's just one example from our city's main A and E: luckily, it was a Saturday lunchtime - but the stories the doctors and nurses have about Friday and Saturday nights would make your hair curl 
It's a combined problem - not enough services to go round, plus too many idiots misusing them.
