The Queen was joined by a special guest as she began her annual tour of Scotland on Monday.

Prince William was pictured with his grandmother as she arrived for what’s known as Royal Week or Holyrood Week, which takes place each summer and celebrates “Scottish culture, achievement and communities.”

Her Majesty and William, known as the Earl of Strathearn in Scotland, visited the Irn-Bru factory in Cumbernauld, with the Queen looking as elegant as ever in a blue ensemble as she posed in front of the bright orange beverage.

The royals officially opened the factory’s new process facility and met employees.
