Andy Murray was in a "impossible position" when posing with the union flag at a photocall, says Graham Bartram, the chief vexillologist at the Flag Institute.

He was speaking to the World Tonight's Shaun Ley after the tennis player's late call-up to be Team GB's flag bearer in Friday's opening ceremony at the Rio Olympics.

It appeared he had not had much chance to practise, when he was sandwiched between the sports minister and the Princess Royal for photographs.
