Clever serving trick to make sure nobody poisons Queen's dinner

But the Queen's evening routine is very, very different when she's not entertaining important figures from around the world.

The Royal Family's state banquets are huge occasions and the hosts and their staff spend months planning every tiny detail.

The guestlist, menu, decoration and speeches are carefully considered to make sure everything is perfect.

Unsurprisingly for events attended by some of the most powerful people in th world, including presidents, prime minsters and royalty, security is also a huge logistical challenge.

Over the years staff have come up with a number of little tricks to ensure our Queen is kept safe during the dinners - including one for ensuring nobody can poison her by slipping something into her food in the kitchen.

In Channel 5's Secrets of the Royal Kitchens, royal correspondent Emily Andrews revealed: "After everything is plated up, a page chooses at random one of the plates to be served to Her Majesty.

"So if anyone did want to poison the monarch they’d have to poison the whole lot."

But the Queen's evening routine is very, very different when she's not entertaining important figures from around the world.

During the programme, Royal biographer Lady Colin Campbell explained that the Monarch's day-to-day tastes are much more modest.

The Queen has her pick of lavish dining rooms but instead she chooses to eat her evening meal in the comfort of her own living room.

And like many of her subjects, the monarch enjoys nothing more than a TV dinner.

Lady Campbell explained: "She has her dinner off a tray looking at the television.

"She likes it. It's homely and cosy and it's comfortable."

Other members of the Royal Family, including Kate and Charles, are regulars at State Banquets.

She has a team of chefs who come up with menu choices for her every few days, which are then presented for the Queen for her to pick she.

Former royal chef Darren McGrady said: "The chef does three days' menus and that gives us enough time to get all the produce in and prepare it.

"When the menu book goes up to the Queen she puts a line through all the dishes she doesn’t want."
