The medical director of Imperial College Healthcare Trust has resigned from the position following an investigation by the trust.

Nick Cheshire had been temporarily relieved of his duties during the probe, which had only been announced last week.

The trust said in a statement announcing the investigation that Prof Cheshire would “not be undertaking his normal duties at the Trust,” during the investigation. “As is usual in these circumstances, all other details of the investigation are currently confidential.”

Days later, the trust released a further statement announcing Prof Cheshire’s resignation and that the investigation had been closed and that no further action will be taken.

Deputy medical director Dr Chris Harrison will take on the role of interim medical director until a permanent replacement is recruited.

A spokeswoman for the trust said: “Professor Nick Cheshire has resigned from his post as medical director and board director.” Prof Cheshire will continue his clinical and academic work at the trust.

Professor Cheshire occupied the co-chief post until April, when the trust collapsed its unusual management structure.

Under this arrangement, he had shared responsibility for leading the trust with two other board members: the trust’s finance director Bill Shields and board chair Sir Richard Sykes.

This triumvirate arrangement – which had been in place since the end of 2013 - came to an end when Tracy Batten took the helm at the beginning of April.
