The trust director who agreed an unusual and “very irregular” exit deal for a senior midwife at the centre of a care scandal has denied any “impropriety”.

Roger Wilson, director of human resources and organisational development at Warrington and Halton Hospitals Foundation Trust, has spoken about the deal he agreed for Jeannette Parkinson, the maternity risk manager at University Hospitals of Morecambe Bay Trust.

An internal review into the deal found that Ms Parkinson “appears to have been significantly overpaid (by as much as 14 months)” under the redundancy agreement when she left Morecambe Bay in spring 2012, HSJ revealed last week. Ms Parkinson was criticised last year by the Kirkup inquiry into failures at the trust.

The summary report of the review seen by HSJ reveals that the unusual deal also saw Ms Parkinson receive more than 470 hours of overtime pay, and included an assurance she would not be investigated in exchange for taking the deal.

In a statement released by Warrington and Halton late on Friday, Mr Wilson, who was at UHMB between 2007 and 2012, said he had been “extremely distressed” by the media coverage about the deal and comments made by Jackie Daniel, the trust’s current chief executive.

Mr Wilson said: “I would like to record that I strongly refute any allegation of impropriety on my part while employed at UHMB or at any other role that I have held in either public or private sectors.”

In the statement Mr Wilson said he had requested a copy of the full investigation report from UHMB to “better understand the broad allegations and the substance behind them”. “Unfortunately, to date, UHMB has elected not to share any of this with me,” he said.

Asked about this issue, Morecambe Bay FT told HSJ Mr Wilson had requested the full investigation report from it on Friday and it would be sent to him today.

A summary report of the investigation was sent to Warrington and Halton Hospitals’ chief executive Mel Pickup several weeks ago.

Mr Wilson added in the statement: “As Jackie Daniel has confirmed, I have fully and voluntary supported the preliminary fact finding into UHMB’s handling of Ms Parkinson’s departure and will continue to cooperate with any further enquiries that take place in relation to this matter.”

Warrington and Halton Hospitals will have a meeting with the Care Quality Commission next month to discuss the events.

Last week, Sir David Henshaw, who was chair at Morecambe Bay in 2012, and now holds the same position at St George’s University Hospitals Foundation Trust, said he was unaware of the agreement.
