Campaigners are due to hold two events to protest against a march organised by the English Defence League (EDL).
The far right extremist group was due to hold a demonstration in Walthamstow on Saturday, August 18, but has now postponed it until Saturday, September 1.
Umbrella campaign group We Are Waltham Forest has reacted by opting to hold two demonstrations in Walthamstow town square on both dates.
A spokesman for the group said: “We have to ensure both dates are well covered, so we need people to be understanding and to turn up in large numbers to show the EDL that we don’t want them or their politics in our borough.”
Both its town square demos will begin from 11am.
