Queen Elizabeth II is set to have a meeting with U.S. President Joe Biden and First Lady Jill Biden next week at Windsor Castle, according to Buckingham Palace.

Biden will be the 12th serving U.S. president that the Queen has met as monarch.

Queen Elizabeth II has also met former President Donald Trump and First Lady Melania Trump at Buckingham Palace in 2019, according to a BBC News report.

Biden will also be meeting British Prime Minister Boris Johnson on June 10 to affirm the enduring strength of the relationship between the United States and the United Kingdom, according to the White House.

Aside from the visit to the United Kingdom, the president will also be visiting Belgium and Switzerland, according to an ABC News Go report.

The meeting with the president and the first lady is the Queen's first major meeting with a world leader after Prince Philip's death in April.

U.S. Presidents Meeting with The Royals

Biden has previously met with the Queen's firstborn son, Prince Charles. Prince Charles is also the heir to the throne.

The two had met during a visit to Washington in 2015 while Biden was serving as the United States' vice president.

Biden had also met Prince Harry in 2017 when he and former President Barack Obama traveled to the Invictus Games in Toronto.

Meanwhile, the Queen had also met with Trump in 2019. Trump also visited in 2018, having tea with the Queen at Windsor Castle during a less ceremonial working visit.

The former president's visit had hit the headlines after he arrived 15-minutes late for a meeting with the Queen. Trump had also broken a royal protocol when he walked ahead of her as they inspected the Guard of Honour.

Former First Lady Michelle Obama had also raised eyebrows when she put her arm around the Queen.

However, Buckingham Palace issued a statement and said that it was a mutual gesture. They also denied that there are rules about touching the Queen.

The Queen is considered the world's longest-reigning living monarch. She has met with all American presidents since 1951, aside from President Lyndon B. Johnson.

Next year she will be marking her 70 years on the throne, which is also known in Britain as the platinum jubilee, according to an NBC News report.

Windsor Castel is an English royal residence in the county of Berkshire, England.
