A ruling that a train drivers' union acted unlawfully when it expelled a British National Party (BNP) member, has been overturned.
Jay Lee, 34, from Bexley, south-east London, was thrown out of Aslef when the union made the discovery.
Mr Lee, who stood as a candidate for the far right group, had complained to an employment tribunal about his removal two years ago and won.
A new hearing will take place after the Employment Appeals Tribunal's decision.
Aslef says it believes it has been vindicated for the expulsion and has a "very strong case".
Shaun Brady, general secretary of Aslef, said: "This ruling vindicates
"We have no place in our union for racist views, and we will seek
to expel members who promulgate these unrepresentative attitudes.
"Train drivers work in a multiracial environment and as their union we wish
to reflect the community that we serve. "
