The Duchess of Edinburgh was absent from Wednesday night's banquet at Guildhall, sparking questions from royal fans on social media.

The Duke of Edinburgh made a solo appearance at the formal dinner with Emperor Naruhito  as they continued their state visit in the UK.

Buckingham Palace previously shared in a press release that Sophie was scheduled to join her husband at the banquet, however, HELLO! understands that this was an error and it was only due to be the Duke of Edinburgh at the event.
