Three of Britain’s victorious women’s hockey team, golf champion Justin Rose, rowers Helen Glover and Peter Reed and cyclist Callum Skinner were the other Britons whose confidential files were among a fourth wave of leaks by the Fancy Bears group, which claims to be exposing Wada-sanctioned “doping” but which has been accused of a revenge attack over Russia’s bans from the Olympics and Paralympics in Brazil.

Farah’s use of medical exemptions came under scrutiny last year when Salazar, his coach since 2011, was accused of doping offences including the abuse of the TUE system.

As well as vowing to sack the American if found guilty, Farah disclosed his TUE history, initially stating he had been granted only one – after he collapsed in a Utah apartment in 2014 – before confirming he had been given another six years earlier for what his camp described last night as an “anti-inflammatory treatment to an injury”.
