It needs to be emphasized that in Britain, if you are willing to pay a private doctor for health care, you can. So those who suffer most are the poor, or those unwilling to spend their own money after paying high taxes for health care. Also, if you use a private doctor, you may lose your access to the NHS.
Though the rot in the NHS is bad, a far worse situation exists in Canada where you must leave the country to get good, private health care, as the government does not permit the private alternative in the country. While Britain is a disaster, Canada will be a worse disaster in the long run. It only looks better right now because so many Canadians cross the border for their medical needs.
