They include a version of Banksy’s Napalm, which shows the girl – nine-year-old Kim Phuc – from a famous 1972 photo of people fleeing a napalm attack during the Vietnam War, made to look like she’s holding hands with Mickey Mouse and Ronald McDonald.
Martin said X sold it for £13,000 but told the presenters they had received £11,000, leaving “a discrepancy of £2,000”.
The disclosure order will allow them to obtain relevant information from art dealer Andrew Lilley and his firm Lilley Fine Art Ltd, which were involved in buying works from Ant and Dec and selling works to them, the court heard.
Lilley and his dealership are not accused of wrongdoing but were “mixed up in the wrongdoing” and were “involved in the flow of money”, Martin told the court.
Lilley has previously refused to give information about the transactions, citing confidentiality, but said he would comply with any court order, the court heard.
Lilley told BBC News he had been “caught up in this mess and it really has nothing to do with me”.
“I was just purchasing art on what I thought was fair and market value, no idea what was going on in the background,” he said.
“This is a matter for the courts now and between A&D [Ant and Dec] and the third party [X].”
