King Charles III and Queen Camilla continued their four-day state visit to the US on Tuesday with their arrival at the White House, an aircraft fly over, a military ceremony and a meeting in the Oval Office.

The trip, which comes as the US approaches the 250th anniversary of its independence from Britain, is aimed at celebrating the strong relationship between the two countries.

The Royals arrived on Monday by plane at Joint Base Andrews, Maryland, to a waiting red carpet.

After walking through a guard of honour, a military band played both the US and UK national anthems.

The royal couple then went on to meet Donald and Melania Trump at the White House for afternoon tea.

The royal couple were shown a beehive shaped like the White House, part of a long-running honey-making programme.

The King and Queen attended a British embassy garden party, where the King chatted with former speaker of the House of Representatives Nancy Pelosi among other guests.

On Tuesday, the royals received a ceremonial welcome at the White House, where President Trump presented a military spectacle to the King and Queen, including gun salutes and bugles.

President Trump gave a speech in front of the White House, in which he joked it was a beautiful British day - an apparent reference to the rainy conditions, which drew laughter.

Trump said the King's speech to Congress later was "going to make everyone very envious of that beautiful accent".

"He's a very elegant man," Trump said, before describing "the noble spirit of the British" and discussing the UK and US's shared history.

Following Trump's remarks, the King, Queen, president and first lady walked up the steps to the balcony overlooking the White House South Lawn to observe a flyover and troops marching below.

Later in the day, King Charles and President Trump held a closed-door meeting inside the Oval Office.

Senior British and American officials were also present during the meeting.
