NHS whistleblowers 'bullied' for raising concerns

Thousands of NHS staff have been bullied and intimidated by senior colleagues after raising concerns about patient care, according to an official inquiry.

The chairman of the inquiry, the barrister Sir Robert Francis, has told the BBC a significant proportion of health workers in England were afraid to speak up when they saw poor care or failings in patient safety.

But he said there had been progress in improving accountability.
