Five more gold medals are decided at the London Stadium on day five of the World Championships, presented by Gabby Logan. South Africa's Olympic 400m champion and world record holder Wayde van Niekerk is attempting a 200-400m double in London and goes for gold over the longer distance on Tuesday night, while the finals of the men's 800m, steeplechase, pole vault and women's javelin all promise to be titanic tussles. Eight-time world champion Michael Johnson is alongside Gabby to provide opinion and analysis, with commentary by Steve Cram, Andrew Cotter and Steve Backley.
