The King has welcomed the president of Indonesia to Buckingham Palace with a traditional sembah greeting.
Charles clasped his hands together in front of his face – an Indonesian gesture of respect – as did President Prabowo Subianto.
The president, who was wearing a traditional black hat, was visiting the monarch for an audience on Thursday morning.
On Tuesday evening, the monarch and the Queen hosted a glittering reception for hundreds of guests at the annual Diplomatic Corps reception.
