Boris Johnson may be the most colorful mayor in the world.
Known for his wit – and sometimes gaffes – the top man in London sports a floppy blonde mop of uncombed hair.
When he wants to promote the bike share system nicknamed after him – Boris Bikes – he rides them up to strangers in shopping malls.
When he wants to promote the Olympics, he ziplines in full suit, waving a tiny Union Jack in each hand. The fact that he got stuck twenty feet off the ground halfway down was just “the only piece of transport infrastructure that seriously malfunctioned” during the Games, he says.
“I'm deliriously happy,” Johnson told CNN’s Christiane Amanpour at his office overlooking the Thames and Tower Bridge on Monday. “I'm deliriously happy and lucky to be mayor of London.”

In his first international trip, Pope Francis has travelled to Brazil, a country wracked in recent weeks by massive street protests.
So is the pontiff, with his message of social change and revival within the church, endorsing the activism of Brazilian youth?
“The core message that he's trying to deliver to young people on this trip is that he wants young people to see themselves as inserted into the struggles of society,” CNN Senior Vatican Analyst John Allen told Christiane Amanpour from Rio de Janeiro on Wednesday.
