The bill for the king of Saudi Arabia's summer break to Morocco is expected to come in at $100m (£77m), as the ruler ships his enormous entourage to the North African state.

King Salman of Saudi Arabia flew into the port town of Tangier, between the Atlantic Ocean and the Mediterranean Sea, at the end of July where he has a 74-acre summer palace.

Major renovation was carried out at the estate last year, including the addition of new buildings, helipads and a big top tent to entertain guests.

The sprawling complex, near Cape Spartel, above the beaches of Jbilia, also includes its own medical facilities and luxury restaurants.

But the estate will only house those closest to the king. In all the royal party is made of over 1,000 people including ministers, advisers, relatives and security staff.

The 81-year-old king has booked around 800 hotel rooms in some of the city's most exclusive hotels, hired about 200 cars, and made arrangements with the city's finest caterers.

Last summer the king used an exclusive fleet of black Mercedes and Range Rovers to ferry his entourage around the city.

The month-long trip is expected to account for 1.5% of Morocco's annual foreign-tourism revenue, estimated to be $6.5bn this year, according to Israeli newspaper Haaretz.

King Salman was met by Moroccan Prime Minister Saadeddine Othmani when he landed Ibn Battouta Airport in Tangier, which is not surprising when the annual summer jaunt has become known as, the world's most expensive all-inclusive package holiday.

King Salman owns properties around the world including several apartments in Paris, a chateau on the Côte d'Azur in France and a palace in Marbella. But the Tangier property is understood to be his favourite.
