The country's top nurse resigned yesterday in the wake of the NHS pay rise blunder that misled thousands of nurses.
Janet Davies, chief executive of the Royal College of Nursing, announced she will step down from her role at the end of August.
She apologised to the 435,000-strong union last month after telling members they would receive an immediate three per cent pay rise this summer.
But only half received a pay rise straight away – the rest were told they had to wait the best part of a year until their appraisal.
Ms Davies offered a 'sincere personal apology' at the time and said the pay deal was 'not as straightforward as we said'.
Maria Trewern, chairwoman of the RCN council said: 'The RCN and Janet Davies have decided to part ways by mutual agreement.
'We thank her for all her service to the college as chief executive and general secretary over the past three years, and wish her well.'
Ms Davies, who had been in her role since 2015, said: 'It has been a great honour to represent my profession at the highest level.
'And I am proud of the achievements the college has made over the past three years against a difficult political backdrop.
'I wish my colleagues and our membership all the best for the future, and look forward to taking on some new challenges.'
Ministers in March finally drew a line under the public sector pay cap as a new NHS deal was unveiled.

The move marked the end of seven years of tough pay restraint as the Government fought to balance the books in the wake of the credit crunch.

The largest NHS trade unions welcomed the
