BYOB (Bring Your Own Booze)

Whether to enjoy on the flight or when they land the royals bring their own alcohol with them on trips.

According to royal reporter Gordon Rayner this is a precautionary measure to ensure their drinks don't get spiked.

He said: “They sometimes take their own alcohol so there’s no danger of their drinks being spiked,

“Their police bodyguard will discreetly carry a bag of their drinks.”
