Jimmy Carter was one of the 13 U.S. presidents Queen Elizabeth met during her record reign, and meeting her also allegedly included an awkward exchange between Carter and the Queen Mother. All about the reported story and protocol around meeting members of the British royal family.

The British media has previously reported that the late president once placed his lips on the late royal matriarch's lips when he came to visit Buckingham Palace in 1977.

The late former US president Jimmy Carter was a relative novice at international diplomacy when made his first visit to the UK just four months into his term in the White House in 1977 – which resulted in him earning the displeasure of the Queen Mother after being said to have given her a parting kiss on the lips.
