Prince Harry will "make every effort" to attend his son's fourth birthday party after King Charles' Coronation.
The Duke of Sussex has confirmed he will return to the UK for the historic day on May 6, while his wife Meghan Markle will remain in California with their children Prince Archie and Princess Lilibet.
Harry is expected to only attend the Coronation ceremony before heading back home for an "intimate" birthday party for Archie.
