A former health boss has claimed he was the victim of unfair dismissal and is seeking legal advice, it has emerged.
Richard Bourne was sacked from his role of chairman of the Colchester Hospital University NHS Foundation Trust weeks after being reappointed to the post.
His removal from the organisation - which provides healthcare services to around 370,000 people - came amid concerns over death rates and waiting times.
Mr Bourne was told to leave his £40,000-a-year role by health watchdog Monitor.
Speaking to the Daily Gazette, he said: "It is disappointing. If it had taken the decision in March, I could understand that."
He added that, while Monitor is "very good" at dealing with financial issues that are "mainly very clear-cut", it is not so strong on other issues.
Former leader of University College London Hospitals Sir Peter Dixon has now taken over as chairman of at the health trust.
