The 'Topless Tongan's' Tokyo Quest

In 2016, Pita Taufatofua became an overnight viral sensation after walking out topless, oiled up and wearing traditional Tongan attire at the Rio Olympic opening ceremony - a trick he repeated two years later in sub-zero temperatures at the 2018 Winter Olympics.

BBC Sport's Nick Hope visits the taekwondo fighter turned cross-country skier in his homeland to learn about the Tongan's humble beginnings and follows the history-making athlete as he bids to qualify for a third successive Olympics in a third different sport.
