LONDON: Prince Charles has turned down an invitation to appear on the British science fiction TV programme Doctor Who.

The show’s writer and executive producer Russell T Davies wrote to Clarence House asking if Prince Charles would like to make a cameo appearance in the BBC drama, reports dailymail.co.uk.

“He turned us down, the miserable swine,” Davies said at the Cheltenham Literature Festival.

A Clarence House spokeswoman, however, dismissed reports Prince Charles had turned down the request. “We receive many requests and it’s impossible to accept all of them,” she averred.
