King Charles left fashion designer Stella McCartney flustered after she forgot how to greet him at a Buckingham Palace reception ahead of the the UN climate change summit Cop27.
The King hosted the reception for politicians and business figures from across the globe with notable guests also including the Prime Minister Rishi Sunak and John Kerry, the US Special Presidential Envoy for Climate.
Mr Sunak was seen introducing the daughter of Beatle Sir Paul McCartney to the King, who has met the designer and worked together with her several times in the past when he was Prince of Wales.
