16. An invitation to dinner with Queen Elizabeth in Abu Dhabi, 1979
But it was also an indication of the deep friendship between the rulers of Britain and the Emirates. "Most striking was the time she spent with His Highness Sheikh Zayed and with others from the ruling family," says Dominic Jermey, the current British ambassador to the UAE.
"The queen had a private meeting with Sheikha Fatima, which she greatly enjoyed and one of the reasons why she returned in 2010 was to have another private audience with Sheikha Fatima."
Elizabeth spent three days in the country, sailing from Abu Dhabi to Dubai, opening a number of projects, meeting the British and local communities and hosting a reception on Britannia, for which the official invitation is shown here.
The ambassador takes up the story: "There was a dinner first - it was a state banquet - which was Her Majesty's way of returning the hospitality of Sheikh Zayed and the other Rulers.
"This was an enormous affair. It had representatives from all the ruling families, from the military, from across the Government as well many people from the British community.
"After the banquet, Sheikh Zayed retired and there was a reception for an even larger group of people. So this was entertainment on a grand scale."
As ambassador, Jermey's responsibilities include more than 100,000 British citizens now living in the country. "Some of them have been here for 50, 60 years," he says.
"They are as much a part of the history of the UAE as the British community is part of the future of the UAE."
