King Charles and Queen Camilla's state visit to the US will go ahead "as planned", Buckingham Palace has said, after a shooting incident in Washington DC raised security concerns.
A statement on Sunday said the decision had been made "after discussions on both sides of the Atlantic through the day".
It is understood there will be minor adjustments to some of the engagements to further minimise risks.
Security concerns were raised after a gunman attempted to storm the White House Correspondents' Dinner at a Washington hotel on Saturday night. The acting US attorney general says the suspect was likely targeting President Donald Trump.
The palace said the King was "greatly relieved" to hear the US president, Melania Trump and other guests had been unharmed.
It's understood the King and Queen privately reached out to the Trumps to express their sympathies for those caught up in the attack.
President Trump and other senior administration figures were evacuated from the dinner after a man fired several shots while attempting to enter the venue. The suspect, identified in US media as 31-year-old Cole Tomas Allen, was detained at the scene.
That had prompted talks about the security around the King and Queen's four-day visit, which begins on Monday, concerning "to what degree the events of Saturday evening may or may not impact on the operational planning for the visit", the Palace had earlier said.
Announcing the visit will now go ahead, the Palace said the King and Queen were "most grateful to all those who have worked at pace" and were "looking forward to the visit getting under way tomorrow".
Acting US Attorney General Todd Blanche said he was "very confident" the King and Queen will be safe during the four-day visit, telling NBC News that Saturday night's incident showed the US security system worked.
Senior government minister Darren Jones told the BBC earlier on Sunday that the King's state visit would have "appropriate security in place in relation to the risk".
Shadow home secretary Chris Philp, meanwhile, said that it was "vital" the King was properly protected, and urged US and UK teams to review the monarch's security overnight.
One Secret Service agent was shot during the incident on Saturday night but was saved by his bullet-proof vest, the president said. No other injures were reported.
Even before that incident, security for the King and Queen's state visit was going to be very tight. Now it will be going up another level.
When Trump visited the UK last autumn, almost all the events happened inside Windsor Castle. He was carried by helicopter in and out of that secure bubble, and so was kept away from any contact with the public.
It is not yet clear what adjustments have been made to the trip. The King had been expected to address both houses of Congress, visit the 9/11 memorial in New York and attend a wreath laying to honour fallen US and UK soldiers in Virginia.
The state visit has already proven diplomatically challenging for those planning it.
It is due to take place days after reports emerged that the US could review its position on UK sovereignty over the Falklands Islands.
Trump has also been highly critical of the UK government and other allies over their response to the Iran war.
But despite these political differences, the US president has been steadfast in his admiration for the monarchy and the King, telling the BBC earlier this week that the state visit could help repair relations between the US and UK.
"I know him well, I've known him for years," the president said. "He's a brave man, and he's a great man."
Sir Keir Starmer offered his "best wishes" to Trump and Melania following the "shocking scenes" that unfolded on Saturday night.
The UK prime minister expressed his relief that the president and first lady were safe in a phone call on Sunday, and wished a speedy recovery to the injured officer.
Liberal Democrat leader Sir Ed Davey likewise condemned the "really shocking scenes", writing on X: "Political violence is wrong. We must all condemn this attack and be thankful no lives were lost."
Reform UK leader Nigel Farage said it was a relief that all attendees were safe, adding: "However much we disagree about politics, if violence is used we all lose."
