LONDON (AP) _ Britain's royal family has given a TV crew unprecedented access to Windsor Castle for a documentary series about life in the royal household.

Buckingham Palace said Thursday that a team from production company RDF had been filming at the castle, west of London, for a year. The three-part series, tentatively titled, ``Windsor,'' and due to be broadcast by the British Broadcasting Corp. next fall, includes an interview with Prince Philip and several scenes featuring Queen Elizabeth II.

A palace spokeswoman said Philip would speak about his role as a ranger for the castle's extensive grounds and parks.

RDF, best known for producing reality TV series ``Faking It'' and ``Wife Swap,'' said it had sold television rights to the series to the Public Broadcasting Service in the United States, as well as broadcasters in Canada, Australia and Germany.
