Some 40 Britain First fascists were humiliated in Rochester, Medway last Saturday.
They tried to march through the High Street after they were blocked by a counter protest earlier this month.
But a mobilisation of some 300 anti-fascists confronted them again, including delegations from CWU, RMT, NUT and Unite union and Unite Against Fascism (UAF).
Many faith groups and local people also joined the demo.
Demonstrators stood behind a Rochester Against Fascists banner, and blocked Britain First for more than hour.
They were eventually escorted out of the High Street to cheers from anti-fascists.
The triumphant counter demonstration was addressed at the end by trade union and UAF speakers.
