The Liberal Democrat conference has just voted - overwhelmingly - to put a brake on what many see as the beginning of the end of nationalised, publicly-delivered health care in the UK.
Andrew Lansley's Health and Social Care Bill, delivered under the guise of 'necessity' and supported by (endlessly repeated) dodgy statistics, is almost universally hated.
