Prince George, the son of Prince William and Kate, the Duchess of Cambridge, will be christened in a private ceremony on Wednesday afternoon.
Watch our livestream of events outside the little known Chapel Royal at St James's Palace in London, from 1.30pm BST.
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 were named earlier today.
