He reigns over a kingdom where the average salary is around $44,000 (£25,000), but that didn't stop Saudi Arabia's king splashing out a huge $100 million on holiday.

King Salman traveled in style to his favourite holiday spot, Tangier, in the north west of Morocco, along with an entourage of more than 1000, who were booked into luxury hotels.

The king himself stayed in his 74-acre summer palace, one of his many properties around the world, which boasts lavish restaurants, and impressive views of the sea.

Expenses during the month-long break included more than 200 cars, Israel's Haaretz newspaper reports.

The 81-year-old's summer palace has been renovated extensively over the past 12 months, with helipads among the features added.

According to reports in Morocco, King Salman's trip accounts for 1.5 per cent of the country's foreign tourism revenue.

When he arrived at the Ibn Battouta Airport, the king was greeted by Moroccan Prime Minister Saadeddine Othmani, the Daily Mail reported.

King Salman opted to go on vacation at a time of high tension in the Gulf, with Saudi Arabia locked in a political row with Qatar which has seen transport links to Doha severed since June.
