Naomi Campbell v Hugo Chávez

The model interviewed the Venezuelan president for February issue of GQ magazine in 2008. "I believe if he wasn't the president he'd be a very successful Latin singer," she deduced, before concluding: "For me his role will always be that of a rebel angel." Campbell was more political than the model's effort with Vladimir Putin, however, with Chávez revealing that he believed George Bush wanted to kill him.

Little Ant and Dec v Tony Blair

Blair agreed to be quizzed by the cherubic TV stars in 2005. The then prime minister admitted that deputy John Prescott had a grumpy face before revealing a fondness for chips. Blair was to call on his experience of tough questioning when he appeared before the Chilcot inquiry five years later.

Sean Penn v Raúl Castro

In November 2008 the Oscar-winning actor interviewed Castro, the Cuban leader using the chat to offer to meet with Barack Obama, once the American took office in what would have been the first official meeting between leaders of the two countries since brother Fidel took power in 1959. In late 2009 the blogosphere was alive with speculation that Penn was to interview Fidel Castro for Vanity Fair magazine, but it never materialised.
