British Prime Minister Tony Blair paid a fleeting visit to Saudi Arabia on Saturday for talks with Crown Prince Abdullah.
Blair spent around three hours in the Saudi capital Riyadh on his way to Singapore, where he will lobby members of the International Olympic Committee in support of London's bid to host the 2012 Games.
The visit to the Middle Eastern kingdom was his first since 2001 and comes amid uncertainty about Saudi Arabia's future, with reports that King Fahd has been seriously ill.
The King, who is believed to be 82, suffered a debilitating stroke in 1995, and Abdullah has served as de facto ruler since then.
King Fahd was hospitalised in May with pneumonia, sparking renewed speculation about the succession.
Downing Street said Blair and the crown prince discussed the upcoming G-8 summit at Gleneagles in Scotland and the prime minister's plan for assistance to Africa and action to tackle global warming.
