Three non-executive directors at troubled Sherwood Forest Hospitals Foundation Trust have announced they will be stepping down.

Vice-chair Bonnie Jones will leave at the end of this month, David Heathcote will leave by 3 November and Iain Younger will leave on 30 November at the end of his term of office.

It comes as regulators Monitor and the Care Quality Commission are taking joint action against the trust, which was found to be in significant breach of its authorisation last month, because of its increasingly poor financial situation.

Earlier this month “emerging concerns” over breast cancer services at the trust prompted Monitor to request a “deep dive” investigation into wider care quality at the trust by the CQC.

Its chair Tracey Doucet resigned at the start of October.

Chris Mellor, the newly appointed interim chair at the trust, said:  “This is a personal decision taken by each of the individuals. I would like to take this opportunity to publicly express my thanks to Bonnie, David and Iain for their commitment and loyal service over the last few years.

“They have helped the board steer the organisation through its formative years as a foundation trust, through the creation of the fantastic King’s Mill Hospital, and towards the focus on quality and safety within our hospitals.

“I would also like to reassure our local communities that the continuity and quality of patient services will be maintained at all times in our continued development.”
