An auditors' report on the controversial pay-off of a trust chief executive and the employment of an interim replacement at more than twice his salary will not be made public until July.

A patient and public involvement forum asked the Audit Commission to investigate after University Hospitals of Leicester trust chief executive Peter Reading stood down last September. He was paid around£170,000 a year and received a£700,000 pay-off - mainly in pension enhancements.

Interim chief Derek Smith got£100,000 plus living expenses for an initial three months' work. He is still on the same rate and will stay until the trust's new chief executive starts in May.

The Audit Commission asked auditors KPMG to look into the payments. But the report has not been made public, although some of it may be included in the trust's annual audit letter due in July.

Former patient forum co-chair David Gorrod said: "There is no point in requiring a publicly funded body to provide value for money if there is no way it can be held to account." A trust spokesman said it was aware the matter had been discussed by the scrutiny committee and the auditors' report would be published in July.
