Mo Farah watched in near-silence as his wife launched a foul-mouthed tirade against an airline worker because the family were told to wait alongside economy passengers, a shocked eyewitness has revealed.
The Olympic hero's partner Tania was said to have been furious when the couple and their daughter Rihanna were told they had missed first-class boarding as they made their way back from Rio.
Asked to wait until all passengers from the gate had boarded before they could make their way on to the plane, Mrs Farah, 30, began swearing at the attendant, it is alleged.
Waiting flyers heard the wife of the four-time gold medal winner call the woman, 'f****** pathetic', tell her she led a 'sad little life' and say she was being 'disrespectful' to the family, it is said.
According to the witness, the outburst - in the presence of Farah's 11-year-old stepdaughter and other young passengers - went on for up to ten minutes as the Delta Air Lines worker failed in her attempts in calming Mrs Farah down. The witness said this only prompted her to add: 'I demand an apology for the way we have been treated.'
