• Howman: ‘We are not effective enough at catching cheats’

• Former Wada director general urges more ambition

One of the most senior figures in global anti-doping has warned that too many drug cheats in sport are evading detection – and criticised the current system as “ineffective”.

David Howman, the former director general of the World Anti-Doping Agency (Wada) and the chair of the Athletics Integrity Unit, urged anti-doping bodies to be more ambitious in catching elite athletes again rather than focusing on compliance issues.
