LONDON: British Prime Minister David Cameron on Tuesday revealed he was “tucked up in bed” by US President Barack Obama during the pair's recent trip on Air Force One.

The two leaders were repeatedly seen back-slapping and sharing jokes during Cameron's recent US visit, but now it appears the friendship was sealed when the president offered Cameron the use of his personal quarters.

“It was 4 o'clock UK time so he (Obama) said 'David, why don't you use my bed and put your feet up,' so I duly did,” he told members of his constituency in Witney, south England.

“Barack went to the back of the plane and explained to my private secretary and the team 'don't worry, the British Prime Minister is fine I have just tucked him up in bed'. I don't think that has happened before,” added Cameron.

Obama went out of his way to hail America's “indispensable” relationship with Britain during last week's visit, even offering to learn the rules of cricket, gifting his guest a top of the range American grill, and laying on a sumptuous state dinner.
