King Charles seems to have been awkwardly forced to step in and move US president Joe Biden along yesterday as they inspected troops during a meeting at Windsor Castle.
His Majesty warmly welcomed the American leader into the castle's quadrangle as he shook hands with Mr Biden while a guard of honour stood nearby.
The president who is on a flying visit to the UK was greeted with the American national anthem being played by the Band of the Welsh Guards when he arrived.
Mr Biden walked onto the grassed area of the quadrangle with the King to inspect the Guardsmen who stood in two rows, the Mirror reports.
However at one point, the president stopped to chat to one of the guards and Charles appeared to step in to hurry the president along who seemed keen to continue with the conversation.
Despite the awkward moment, the two men seemed to get along well and returned to the dias in the quadrangle, where Joe Biden was even seen putting an arm around the King's back.
It came just moments after the two pair were seen sharing a joke, with the president even touching the King's right arm with his free hand as Charles returned the gesture.
After the welcome ceremony, the pair had tea in His Majesty's personal sitting room known as the Oak Room which overlooks the castle's famous Quadrangle.
Their meeting over tea lasted around 20 minutes which is reportedly longer than planned as the two men had hit it off so well.
After this, the King invited his special guest to view the impressive display of items from the Royal Collection in the White Drawing Room which were all related to the Royal Family's relationship with previous US presidents including Roosevelt, Kennedy and Eisenhower.
The display included a letter from Queen Elizabeth II to President Eisenhower following his visit to Balmoral Castle in 1959.
Penned in January 1960, it features a recipe for the 'drop scones' the President had so admired during his visit to her beloved Scottish home the previous year.
The letter was chosen as this visit also marked the first time a young Prince Charles who was then just 10-years-old had met a serving US President.
Biden's visit continued into the Green Drawing Room where two uniformed members of staff had patiently waited several minutes to dramatically open a set of magnificent golden doors to present their arrival.
Inside the drawing room were around 50 to 60 participants of the Climate Finance Mobilisation Forum, who had met earlier at a nearby hotel.
The Forum has brought together financial and philanthropic leaders from the UK and the USA to strengthen commitments to climate action with emerging markets and developing economies.
Charles and Biden stood next to each other smiling as they were briefed on the morning's activities by energy secretary Grant Shapps and John Kerry, the US Special Presidential Envoy for Climate, before making their way around the tables to meet the representatives.
Outside the grand windows, no less than five presidential helicopters could be seen parked on the lawn of the East Terrance.
They were accompanied by a fleet of more than ten vehicles that escorted President Biden from the helicopter to the castle.
Mr Biden also met with the UK prime minister Rishi Sunak ahead of his visit to Windsor Castle amid a huge international backlash over the use of cluster munitions in Ukraine.
The two leaders smiled and shook hands before heading to the garden for crunch talks ahead of a Nato summit in Lithuania tomorrow.
Ahead of the half-hour meeting Mr Sunak was urged to press Mr Biden on the decision to send cluster munitions to Ukraine having said he "discourages" their use.
