Mr Massey will take up the role of GMC chief executive ‘towards the end of 2016’, the GMC said.
He is currently a director general at the DH – a role he has held since 2012 – and has previously worked in senior positions at the Department for Work and Pensions, HM Treasury and the Pensions Regulator.
Mr Dickson, whose tenure oversaw the launch and implantation of medical revalidation, announced in January that he was stepping down from the post after seven years.
The new chief executive will ‘build on the reforms delivered under Mr Dickson’s leadership’, according to the GMC.
Mr Massey said: ‘I am delighted to be joining the GMC and look forward to working with the chair, council and staff to build on the reforms of the last decade.
‘The GMC is an independent patient safety organisation and I share its ambition to work closely with doctors across all four countries of the UK, at all stages of their training and careers, to promote the highest standards of medical practice.’
GMC chairman Professor Terence Stephenson said: ‘We welcome Charlie to the GMC and know that he will bring a wealth of experience to the organisation that will help us protect patients and meet the challenges of regulation in rapidly changing healthcare systems across the UK.
‘During Niall’s time as chief executive, the GMC has moved significantly to become a patient safety organisation.
'With Charlie we will continue that reform by taking forward a number of ambitious projects that will help us to become an organisation that is more responsive to the context in which doctors work, imposes fewer burdens on doctors and the healthcare system and does more to support doctors with the professional challenges they face during their careers.’
