The Duke of York offered to help US officials on “at least three occasions” in the inquiry into sex offender Jeffrey Epstein, his lawyers say.
US authorities have previously accused Prince Andrew of not cooperating with the investigation.
But the duke’s representatives suggested the US Department of Justice was seeking publicity rather than accepting the offer of help.
The duke has been heavily criticised for his friendship with Epstein.
He has previously said he did not witness any suspicious behaviour during visits to Epstein’s homes.
