Is there still an NHS?

Everyone talks about the National Health Service but it has not been national for years. Northern Ireland had a separate health service from the beginning as it only became formally part of Britain after the NHS was created.  Scotland and Wales had their own heath services following devolution.  The county of Manchester is about to have its own health service very shortly.  That makes five separately run and funded health service in Britain.

Depending on the composition of the next government we might well end up with eleven separate health services each with their own government.  It might mean that MPs in the British parliament would have no say over these eleven NHSs (in the same way that the British parliament currently has no say over policies in Northern Ireland, Scotland and Wales).
