The King and Queen have arrived in the US to begin a four-day state visit with President Donald Trump.
Charles and Camilla landed at Joint Base Andrews in Maryland mid-afternoon local time on Monday.
They then met President Trump and First Lady Melania at the White House, followed by a garden party.
The two couples greeted each other outside by the historic building’s south portico overlooking the lawns where past presidents have hosted Queen Elizabeth II.
Camilla wore a brooch pinned to her chest featuring the American stars and stripes crossed with the Union flag.
The trip is a significant diplomatic visit for the King which the UK government hopes will ease tensions with the president.
The so-called special relationship has been under strain in recent weeks owing to disagreements between President Trump and Prime Minister Sir Keir Starmer over the war in Iran.
It also marks the first time a reigning monarch has visited the US in almost 20 years, with the last occasion a trip by Queen Elizabeth II in 2007.
Waiting at the bottom of the steps of the plane was a line of dignitaries prominent among the was the UK’s ambassador to America Sir Christian Turner, who replaced Lord Peter Mandelson when he was sacked over new revelations about his relationship with sex offender Jeffrey Epstein.
The state visit has “all appropriate security measures” in place following a suspected assassination attempt on Trump, the ambassador said earlier.
Charles and Camilla received posies from children of British military families based in the US, before being greeted by the diplomatic, federal and state representatives and walking through an honour cordon formed by US military personnel.
Before they left Joint Base Andrews, a military facility on the outskirts of Washington, a military band played the national anthems of the UK and US.
Minor adjustments have been made to some royal engagements following the shooting at the White House Correspondents’ Association dinner on Saturday evening in Washington.
A man has been charged with the attempted assassination of the president following the incident.
The four-day trip is set to mark the 250th anniversary of American independence and strengthen the special UK-US relationship, which has been under serious strain in recent months.
Security teams in Britain and the US worked through the night assessing the state visit after the president was endangered when shots were fired outside the dinner.
Britain’s ambassador in Washington, Sir Christopher Turner said UK and US security teams had been planning the trip for weeks before the incident at the media dinner, with changes possible “as we go”.
While minor adjustments will be made to one or two royal engagements, the overall plan is understood to remain unchanged.
Buckingham Palace confirmed the visit would “proceed as planned” after discussions were held on both sides of the Atlantic and advice taken from the Government.
