Leadership at the Norfolk and Norwich University Hospital came in for criticism from inspectors at the Care Quality Commission.

The rating of the leadership of the trust went down from requires improvement to inadequate, in a highly critical report by a team of inspectors.But who actually runs the hospital?

The chairman and chief executive share the leadership of the Norfolk and Norwich University Hospital.

The chief executive is Mark Davies, while the chairman is John Fry.

The chairman's role is to lead the board of directors, making sure it effectively governs the trust, while the role of the chief executive is to lead the executive in delivering the strategy and managing operational delivery.

The chief executive is also the officer accountable to parliament.

Mr Davies was appointed as interim chief executive in August 2015 and chief executive in November 2015.

He has more than 20 years' experience as chief executive at trusts including Hammersmith Hospitals and St Mary's Hospital in Paddington.

Immediately before he joined the trust, he was improvement director at Monitor, the independent regulator of foundation trusts.

Mr Fry has been chairman since May 2013. In April 2016 he was reappointed by the council of governors for a second three year term.

He was chief executive of regional media group Johnston Press from 2009 to 2012, and before that was chief executive of Archant, which publishes the Eastern Daily Press and Norwich Evening News.

The executive directors share collective responsibility with the non-executive directors as part of a unified board and shape and deliver the trust's strategy and operational performance.

Other executive members are: Richard Parker (chief operating officer), Peter Chapman (medical director), Jeremy Over (director of workforce) and John Hennessey (chief finance officer). Professor Nancy Fontaine has recently been appointed as the new chief nurse.

The role of the non-executive directors is to bring a range of varied perspectives and experiences to strategy development and decision-making, ensure effective management arrangements and hold the executive to account for performance.

Non-executive directors are Professor David Richardson, Tim How, Mark Jeffries, Angela Robson, Sally Smith and Dr Geraldine O'Sullivan.

What does going into special measures mean (and how do you get out of it?)

Special measures apply when NHS trusts and foundation trusts have serious problems and there are concerns the existing leadership cannot make the necessary improvements without support.

Trusts may be placed in special measures as a result of serious failures in quality of care and/or serious financial problems.

There are currently 19 trusts in special measures, including the Norfolk and Suffolk NHS Foundation Trust, which provides mental health services in our region.

The foundation trust which runs the Queen Elizabeth Hospital in King's Lynn came out of special measures in 2015.

It had been placed in special measures in October 2013, with Care Quality Commission inspectors concerned over A&E services, surgery and leadership.

When it came out of special measures, the 'strong and cohesive' leadership of the then chief executive Dorothy Hosein was praised.
