The Duke and Duchess of Cambridge, Prince George and baby Charlotte, will make their first public appearance as a family at the Princess' christening.

They'll join the Queen, the Duke of Edinburgh, the Prince of Wales, the Duchess of Cornwall and Kate's parents Carole and Michael Middleton at the Church of St Mary Magdalene in Sandringham on July 5 for the traditional ceremony.

Much like the Christmas Day service, members of the public will be allowed to gather nearby to see Charlotte and the royals as they make their way to and from the church.
