London, England (CNN) -- Britain's Prince Andrew has denied knowing anything about his ex-wife Sarah Ferguson's alleged offer to an undercover tabloid newspaper reporter to sell access to Queen Elizabeth's second son for £500,000 ($723,000). His comments came after News of the World posted a video on its Web site Sunday that appears to show Ferguson accepting money from an undercover reporter in exchange for an introduction to Prince Andrew. Ferguson is also filmed on hidden camera telling the reporter -- who was posing as a wealthy businessman -- that a payment of £500,000 "opens doors" to Andrew. She then shakes hands with the reporter after he accepts the deal.
