London CNN  — 

Britain’s Prince Harry will join Queen Elizabeth II at a private lunch with Donald Trump and his wife Melania next month, CNN has learned.

The lunch takes place on the first day of the US President’s state visit to the UK.

Prince Harry’s wife, Meghan, the Duchess of Sussex, is not expected to attend. She has not resumed public engagements since the birth of their son Archie Harrison.

Historically, Harry has only participated in the state visit by Spain’s monarch, where he accompanied the Spanish delegation to Westminster Abbey. CNN’s royal source says that going forward, they hope to see the Sussexes participate in more state events.

Buckingham Palace on Friday also revealed the schedule for Trump’s three-day visit, which starts on June 3.

Day one of Trump’s state visit to the UK

President Trump previously met the Queen during his first official visit to the UK last July.

The President and first lady will be officially welcomed at Buckingham Palace in London by the Queen, Prince Charles and his wife Camilla, Duchess of Cornwall.

Trump will receive a Ceremonial Welcome in the palace garden, and then inspect the guard of honor, made up of Nijmegen Company Grenadier Guards, with Charles. Meanwhile, royal gun salutes will be fired in nearby Green Park, and at the Tower of London.

The Queen will then host a private lunch for her guests before inviting them to view a specially curated exhibition at the Picture Gallery. The display will be comprised of items from the Royal Collection of historical importance to the United States.

In the afternoon, Trump and Melania alongside Andrew, Duke Of York, will head to Westminster Abbey to lay a wreath at the Grave of the Unknown Warrior and take a tour of the World Heritage site. Later – as exclusively reported by CNN earlier this week – the Trumps will join Charles and Camilla for tea at their residence at Clarence House.

The first day will culminate in a lavish state banquet at Buckingham Palace.

June 4 will be a more political affair with Trump joining outgoing UK Prime Minister Theresa May for a breakfast meeting alongside the Duke of York at St James Palace and senior UK and US business leaders.

The President then heads to May’s official residence at Downing Street for talks and lunch, followed by a press conference.

That evening, it will be the Trumps’ turn to host dinner at Winfield House, the residence of the US ambassador, with Charles and Camilla attending on behalf of the monarch.

Day three of Trump’s state visit to the UK

Finally, June 5 will see the Queen alongside Charles and her visitors attending commemorations for the 75th anniversary of the D-Day landings at Southsea Common in Portsmouth. The naval city on England’s south coast was important embarkation site in the World War II operation.

The event – where over 300 World War II veterans will also be present – will include a musical performance, readings, and military displays, including a fly-over of 25 modern and historical aircraft.
