The Princess of Wales will include O' Come, All Ye Faithful in her Westminster Abbey Christmas service after asking Good Morning Britain viewers to vote for their favourite carol.

The royal mother-of-three, 40, gave viewers a choice of three carols to be performed at her Christmas service, which will air on December 24 on ITV1.

This morning, hosts Richard Arnold and Susanna Reid revealed that over 25,000 people took part in the vote this week.

The Princess narrowed the shortlist down to Hark The Herald Angels Sing, Joy To The World and O’ Come, All Ye Faithful - with the latter taking first place.
