The Venezuelan president, Nicolas Maduro, has vowed to keep alive the defiant revolution begun by Hugo Chavez. And that revolution has global radical support. But with growing economic chaos and street protests, it's feared that Venezuela is descending into chaos.

So what has shaped Maduro in his defiance? Can he hold the country together? Chris Bowlby explores his life and career. Producer: Alex Burton.
