The biggest ever rise in public dissatisfaction with the NHS was recorded last year, according to a long-running survey.
The British Social Attitudes Survey has been tracking satisfaction since 1983.
The 2015 poll of nearly 2,200 people showed satisfaction with the NHS at 60% - down from a peak of 70% in 2010.
Some 23% said they were actively dissatisfied - a rise of eight percentage points on the year before and the biggest single jump in a year.
