Donald Trump will arrive in the UK tomorrow morning for his first State Visit since becoming the President.
Mrs Trump and his wife Melania will meet the Queen , Prince Charles and Camilla at Buckingham Palace, and will be officially greeted with a ceremonial welcome.
Months of preparation have gone into the three-day visit, which will include a State Banquet and a trip to Portsmouth.
But the Queen has one very important job to attend to in the lead up to the visit - and it's something she does ahead of every visit.
To set the room up for the banquet, a team of three people spend EIGHT weeks unpacking all George IV's Grand Service, dismantling, washing, polishing and putting it back together again.
Setting up the room itself starts about five days before the event and a dedicated team spends hours making sure everything is just perfect.
All the napkins are embroidered with the Queen's monogram, and are folded by one person so they are all exactly the same.
Each guests has six glasses for champagne, white and red wine, dessert wine, port and water.
There are 2,000 bits of cutlery on the table for 170 guests.
A member of the team measures each of the place settings to make sure every piece of cutlery, glass and decoration is in exactly the right place - to the millimetre.
Once all the decorations have been added, the Queen does a final inspection to check everything is perfect.
She walks around with a member of the staff checking every tiny little details, and points out any changes she wants made.
