Thousands of protesters gathered in Walthamstow, London on Wednesday (August 7), in response to a planned far-right demonstration.
The big crowds gathered without apparent opposition with some police officers standing nearby and police vehicles closing the roads.
Counter-protesters were seen preparing anti-racist banners.
Britain has been hit by a series of riots that erupted early last week after three young girls were killed in a knife attack in Southport, northwest England, triggering a wave of false messaging online that wrongly identified the suspected killer as an Islamist migrant.
