Prince Harry and Meghan Markle have finally sent out the 600 invitations to their eagerly anticipated May wedding after months of fevered anticipation .

Some 600 guests will attend Prince Harry and Meghan Markle's wedding service at St George's Chapel.

Later that evening, 200 guests are invited to the private reception at Frogmore House given by The Prince of Wales.

The invitation stipulates a strict dress code with men asked to don military uniform - likely to be worn by Harry, a former solder who is now Captain General of Royal Marines - or a morning coat and lounge hat, with women asked to wear a day dress and hat.??

The invitations, posted this week, have been produced by company Barnard & Westwood, which has held a Royal Warrant for Printing & Bookbinding by Appointment to Her Majesty The Queen since 1985.??

Using American ink on English card, the invites - on thick white card gilded along the edge - feature printed italic writing and are issued under Charles's name and bear his heraldic feathers embossed in gold at the top.? ?

The invitations are similar to the ones sent out for the Duke and Duchess of Cambridge's wedding in 2011 - although these were in a different font and were issued with the Queen's royal cypher.

The royal couple will marry at St George's Chapel in Windsor Castle on May 19, with millions of people expected to watch around the world.
