At one point, a small group of counter-protesters had attempted to break police lines, said the force.
“They were kept back and reminded that we are keeping the groups apart in the interests of public safety.”
Flag-carrying Britain First supporters were seen letting off smoke flares, and chanting anti-government messages before being addressed on a stage by the group’s leader, Paul Golding.
The “march for remigration” was calling for “mass deportations of foreigners,” he told the crowd.
Mayor of the West Midlands, Richard Parker, said the group was not welcome in the city, saying residents did not share their “divisive and dangerous rhetoric”.
