The Pope will deliver the Christmas Eve Thought For The Day message on BBC Radio 4.
His Christmas message to the British people tomorrow follows a visit to Britain in September – the first official state visit to the country by a pontiff.
It is an unprecedented move, as Pope Benedict XVI is not thought to have presented material specifically written for a radio or TV audience before. The Pope's message will be broadcast at 7.45am during the Today programme. It was recorded in Rome yesterday.
