Speculation has been mounting over whether the couple would be invited after Harry’s outspoken criticism of his family in his memoir Spare.
However, a spokesperson for the couple has confirmed the pair received an email correspondence regarding the event.
“I can confirm The Duke has recently received email correspondence from His Majesty’s office regarding the coronation, “ the spokesperson told The Times.
“An immediate decision on whether The Duke and Duchess will attend will not be disclosed by us at this time.”
It follows reports that Harry and Meghan are set to give up the keys to their current British home, Frogmore Cottage in Windsor, later this year.
It is understood Charles has offered Frogmore to Prince Andrew, who is reluctantly set to leave the 30-room Royal Lodge in Windsor where he has lived for more than 20 years.
Harry and Meghan - who now live in a nine-bedroom £12 million house in Montecito, California, after quitting the Royal Family three years ago - have reportedly been told they have until the autumn to move any belongings out of Frogmore Cottage.
Harry’s stinging criticism of his family in his memoir Spare – released in January – is believed to have left the King and the Queen Consort furious.
