Richard Branson has described hosting the Obamas for their post-presidency holiday in the British Virgin Islands as "an honour".
The billionaire entrepreneur revealed how he challenged former US President Barack Obama to a watersports challenge after Obama revealed he had not been allowed to indulge in his passion for surfing since he was elected into the White House in 2008.
Branson wrote: "One of the first stories Barack told me when he and Michelle arrived on Moskito Island was how, just before he became President, he had been surfing on a dangerous break in Hawaii.
"When he came in from an exhilarating session, the new head of his security team turned to him and said: 'This will be the last time you surf for eight years'.
"For the next eight years he didn't have the chance to surf, enjoy watersports or do many of the things he loved."
