Invitations to the wedding of Prince Harry and Meghan Markle have been posted to 600 lucky guests, with a select 200 close friends invited to an after party at Frogmore House.

Kensington Palace confirmed that formal invitations have been sent by the Prince of Wales, for the May 19 service at St George's Chapel, Windsor.

Some 600 people, including the Royal Family, Ms Markle's parents, and the couple's friends will attend the church service and lunchtime reception, given by the Queen.

Later in the evening, 200 guests will travel to Frogmore House, where the Prince and Ms Markle spent time together as their relationship blossomed.

The invitations, posted this week, were produced by Barnard and Westwood, which has held the "Royal Warrant for Printing & Bookbinding by Appointment to Her Majesty The Queen" since 1985, and has a second royal warrant with the Prince of Wales.
