US President Joe Biden said Britain's Queen Elizabeth reminded him of his mother after meeting the monarch for tea at Windsor Castle in England.
Mr Biden and his wife, US First Lady Jill, travelled to the Berkshire royal residence on Marine One on Sunday after attending the G7 summit in Cornwall.
After tea with the 95-year-old British monarch at Windsor Castle, Mr Biden told reporters: "I don't think she’d be insulted but she reminded me of my mother, the look of her and just the generosity."
He added that the queen had asked about Chinese President Xi Jinping and Russian President Vladimir Putin.
"She wanted to know what the two leaders that I - the one I'm about to meet with, Mr Putin, and she wanted to know about Xi Jinping," he said.
The Bidens landed in the grounds of the castle just before 5pm, a few minutes ahead of schedule, and were greeted by Queen Elizabeth in its quadrangle.
A Guard of Honour gave a royal salute and the US national anthem was played beneath blue skies and hot sunshine.
Mr Biden accompanied the officer commanding the Guard of Honour, Major James Taylor, and Major General Christopher Ghika to inspect the Honour Guard, before returning to the dais to watch the military march-past with the queen and his wife.
As the Bidens walked into the castle with the monarch, the queen said to the president: “You completed your talks.” He replied: “Yes we did.”
Before going inside, the queen introduced the Bidens to her lady-in-waiting Annabel Whitehead.
The palace said the couple left at 6.03pm – meaning they spent around 40 minutes inside the castle, with the whole visit lasting more than an hour in total. It is believed the visit overran by 10 minutes.
The tea in the castle’s Oak Room comes after the Bidens met the queen on Friday when she attended a reception for G7 leaders at the Eden Project.
Trump visit
The carefully-choreographed arrangements to welcome Mr Biden echo the welcome given to Donald Trump in 2018, when the controversial then-US president travelled to Windsor to meet the monarch.
On that occasion however, the queen joined Mr Trump in inspecting the troops.
As they walked across the lawn to view the troops, the queen appeared to gesture and point several times for him to move closer to the front line of soldiers.
Mr Trump moved slightly nearer but then stood still in front of the queen, meaning she had to navigate her way around him so they could walk side by side.
Escorting a visiting head of state to inspect the troops is a role which usually fell to the late Prince Philip, before he retired in 2017.
Mr Trump and the queen had afternoon tea together, also in the Oak Room, with the meeting lasting longer than expected.
It was due to last around half-an-hour, but overran by almost 20 minutes.
The queen also entertained the Obamas at Windsor Castle in 2016 when Prince Philip, then 94, famously drove Mr and Mrs Obama the short distance to the castle after Marine One touched down on the lawns of the residence.
In 2008, when then-US president George W Bush met with the monarch at Windsor, he enjoyed a traditional English afternoon spread of tea, small sandwiches and cakes in the White Drawing Room.
There have been 14 US presidents during the queen’s 69-year reign – from Harry S Truman to Mr Biden.
Mr Biden, who is in the UK for the G7 summit, will be the 13th American leader to meet the monarch, with Lyndon B Johnson the only one the queen has not met.
