King Charles, Queen Camilla land in the U.S. for State Visit

 Britain's King Charles and Queen Camilla arrive in the United States later on Monday for a four-day trip, a tour ​which has taken on even greater prominence after the White House Correspondents' dinner shooting and amid acrimony between the close allies.

The state ‌visit, by far the most high-profile and consequential of Charles's reign, marks the 250th anniversary of the U.S. declaration of independence from British rule, and is the first to the country by a British monarch for two decades.

It begins with a private meeting with self-proclaimed royal fan President Donald Trump, and includes an address to Congress and a lavish dinner at ​the White House.

PRESS DINNER SHOOTING JUST DAYS BEFORE VISIT

But the long-planned trip has become enmeshed in the political spat between the two ​countries over the U.S.-Israeli war on Iran, which led Trump to voice deep displeasure with the British government for failing to support ⁠the offensive.

The shooting on Saturday at the White House Correspondents' Association dinner in Washington, with the president and officials in his administration the likely targets ​according to the U.S. acting attorney general, has cast a further pall over the visit.

Buckingham Palace said the trip would still go ahead as planned following ​discussions between British and U.S. authorities to determine if the incident would impact on the royals' plans.

"The king and queen are most grateful to all those who have worked at pace to ensure this remains the case and are looking forward to the visit getting underway tomorrow," a palace spokesperson said on Sunday.

TRUMP HAS CRITICISED UK OVER ​IRAN STANCE

On arriving in Washington, the king and queen have a private tea with the president, an unabashed lover of the British royal family ​who regularly describes Charles as a "great man", and his wife, first lady Melania Trump.

The 77-year-old king, who is still undergoing treatment for cancer, will address Congress the next day - just ‌the second ⁠time a British monarch has done so.

The royals will then head on to New York where they will commemorate those killed in the September 11, 2001 attacks ahead of the 25th anniversary, while the queen will also mark the centenary of children's stories featuring Winnie the Pooh.

The U.S. trip concludes in Virginia with the king meeting those involved in conservation work, a nod to his half century of environmental campaigning.

The government of British Prime Minister Keir ​Starmer is hoping the visit will shore ​up the future of the ⁠two allies' "special relationship" which is at its lowest point since the Suez Crisis in 1956.

Britain's ambassador to the U.S., Christian Turner, said the visit would underscore the shared history, sacrifice and common values between the two countries, adding ​that the approach would be a very British one of: "Keep calm, carry on."

While Trump has eased his criticism ​of Britain in recent ⁠days over its response to the Iran war, an internal Pentagon email has set out how the U.S. could review its position on Britain's claim to the Falkland Islands as punishment for its lack of support, once again straining ties.
