Queen Elizabeth II previously packed a surprising item during her royal tour of Africa several years ago.

In Robert Hardman’s book “Queen of the World,” the author revealed that there were some security concerns ahead of Her Majesty’s trip to Zambia with Prince Philip and Prince Andrew. However, the monarch still decided to push through with her royal engagement.

“Neither the Queen nor her officials were giving any thought to cancellation. Rather they were already planning their packing. The British High Commission was bombarded with questions… The Master of the Royal Household wanted to know the precise dimensions of the plates that he hoped to use at his state banquet,” Hardman said.

The Master of the Royal Household also required 12 dozen bottles of tonic water and six dozen bottles of soda. The Queen brought her own alcohol to go with it.

Meanwhile, the Queen is not the only member of the royal family who brings alcohol during her overseas tours. According to The Telegraph reporter Gordon Rayner, Prince Charles and Camilla Parker Bowles also bring their own stash of booze whenever they have to travel abroad.

“Prince Charles and the Duchess of Cornwall sometimes take their own alcohol so there’s no danger of their drinks being spiked,” he wrote.

However, Prince Charles already said that this was just a rumor.

In related news, the Queen also made headlines this week after it was revealed that her use of handbags comes with a secret. Her Majesty uses her handbags to send secret signals to her staff while they are out in public.

For instance, if the Queen places her handbag on the table at dinner, this means that she is trying to tell her royal staff that she wants the event to end within the next 5 minutes. If the Queen places her handbag on the floor, it means that she’s not enjoying the conversation and wants to be rescued by her royal staff.
