New Delhi, Oct. 22 -- Prince Andrew has not paid rent on Royal Lodge, his grace-and-favour mansion on the Windsor Estate, for two decades, according to a copy of the leasehold agreement obtained by The Times.

The lease agreement for the 30-room estate, which Andrew and his family are entitled to occupy until 2078, reveals that the prince has paid just "one peppercorn" (if demanded) in rent per year since 2003.
