Sports dopers to face four-year bans

World Anti-Doping Agency leaders have backed proposed tougher sanctions for drugs cheats that should bring an end to the British Olympic Association's aim to revive their lifetime ban for dopers.

Wada will double the ban for serious offences, such as taking steroids, to four years from 2015 under its new draft code.

The BOA's lifetime ban was overturned in the Court or Arbitration for Sport in May after action by Wada but it has continued to press to be allowed to retain control of its selection process.
