Father Federico Lombardi, the Vatican spokesman, pointed out to journalists that the Vatican's security officers - the famed ceremonial Swiss Guard and the 150-strong police force - are there to serve the pontiff, not to restrict his movements.
His personal archive of documents will be packed up and, at 20:00 (19:00 GMT) on Thursday, the Swiss Guard on duty at his Castel Gandolfo residence will be dismissed, to be replaced by Vatican police.
