British swimmer Luke Greenbank, a bronze medalist from the Tokyo 2020 Olympics, was disqualified from the men's 200-metre backstroke heat in Paris for violating the 15-metre underwater rule. Despite finishing first with a time of 1:56.08 and being the fastest qualifier, officials determined he remained submerged too long after his final turn. The disqualification left Greenbank and his supporters devastated, as he had been in strong form and poised for a successful Olympic campaign. His disqualification allowed teammate Oliver Morgan to advance to the semi-finals. Greenbank expressed his frustration and heartbreak, stating he was 'absolutely gutted'. The rule, which mandates swimmers must resurface by the 15-metre mark to ensure fair competition, has led to mixed reactions among viewers and commentators.
