The British Medical Association criticised the new telephone triage system NHS 111 for crashing in certain parts of the country - as well as the quality of advice on offer.
There have been widespread reports of patients being unable to get through to an operator or waiting hours before getting a call back with the health information they have requested.
In some areas, such as Greater Manchester, NHS 111 effectively crashed because it was unable to cope with the number of calls it was receiving.

The quality of advice being given out has also been questionable in some instances.
