Stoke Mandeville Hospital said a report into alleged abuse by Jimmy Savile at the hospital will be published in the autumn because investigators wanted to question further witnesses.
An NHS spokesman said:
Following the emergence of new information, the independent Speaking Out investigation into the actions of Jimmy Savile at Stoke Mandeville Hospital will not now be published before the summer, as originally planned.
Given the nature of the issues under investigation and the importance of hearing from all witnesses, the Trust believes it is important the report is thorough, comprehensive and accurate.
It will now be published in the autumn of this year.
