King and Queen welcome Japanese Emperor to UK

King Charles III and Queen Camilla have welcomed Japanese Emperor Naruhito and Empress Masako to the UK.

A ceremony on Horse Guards Parade, where some of the most prestigious regiments were on display, marked the start of a three-day state visit to the country.

A Japanese foreign ministry official said it was hoped the visit would forge "friendly relations across generations".

It is the first by a Japanese head of state since 1998.
