Former Jersey police officer Lenny Harper will give evidence
The man who originally lead the police investigation into historic child abuse in Jersey will be giving evidence to a government panel.
Lenny Harper will speak to a States of Jersey scrutiny panel, which is reviewing how the appeal was managed.
The Education and Home Affairs Sub Panel is looking at a report by an accountancy firm that criticised the financial management of the inquiry.
Mr Harper will give evidence from the UK over the telephone on Monday.
St Helier-based accountants BDO Alto reported in June 2010, but the States said concerns had been raised about the report's fairness.
Now the States has set up a sub panel to investigate issues arising from the report.
Deputy Trevor Pitman, who is leading the review, said: "We will focus solely on the questions arising from the concerns about how this report was produced."
Police in Jersey began a covert investigation into alleged abuse at the former children's home Haut de la Garenne in 2006.
In 2010, accountancy firm BDO Alto looked into the police inquiry at Haut de la Garenne, which used specialist equipment costing thousands of pounds.
There had been allegations that money was misused. Former deputy chief officer Lenny Harper was criticised.
Mr Harper said it was misleading and drew the wrong conclusions
He said: "They never asked me one question; how can that be an earnest attempt to get at the truth?
"I spent £1,500 more than a deputy chief constable of a small force in West Yorkshire who did not have a major inquiry and who did not have to go across the English Channel every time he went to see somebody.
"The whole thing is full of mistaken assumptions."
