The Duke and Duchess of Cambridge's son Prince George will be christened later in front of close family and friends of his parents.
The three-month-old baby, who will one day be king, will be baptised by the Archbishop of Canterbury, the Most Rev Justin Welby, in the little known Chapel Royal at St James's Palace this afternoon.
The Queen and Duke of Edinburgh are expected to be at the ceremony along with the Prince of Wales, who has become a grandfather for the first time, the Duchess of Cornwall and Prince Harry.
Kate's family - parents Carole and Michael Middleton and siblings Pippa and James - are thought to be invited, along with the godparents who, like the guests, have not been publicly named.

Prince George was christened today in a small, private service at the Chapel Royal at St James's Palace.
Royal christening celebrations are steeped in tradition and history, and Prince George's, though intimate, will be no different.
