Limo at the Castle

I decided on a rare dry evening after work to walk up to Edinburgh Castle and take some pics of it while the seating is up for the upcoming Edinburgh Military Tattoo (it also gets used for some concerts before and after the Tattoo - Blondie played there last weekend. Scarily Debbie Harry is only a few years younger then my mum!). As I was taking pics this Daimler Limousine arrived taking someone into the Castle. I have no idea if it was a member of the royal family, or an official or whoever it was as an ignorant tourist stepped right in front of my camera as the limo passed me so she could take a pic. I wonder who it was?
