On board we spoke to Petty Officer Dean Allen, who works as a chef on board and will be in charge of preparing the meal for the monarch when she visits.

Allen told us that his team submitted several menu ideas ahead of the event, then sent them to officials at Buckingham Palace who made the final call on what should be served.

The lunch, which is for the Queen and 31 other dignitaries, is part of a ceremony in which Her Majesty will formally accept HMS Queen Elizabeth as part of the Royal Navy, a process called "commissioning."

The ceremony will see the Queen visit the ship, inspect a naval guard of honour, and celebrate the beginning of the ship's naval career along with her crew and their families.
