In Cable Street the police tried to force the crowd aside to let the fascists through, and the local dockers, many of whom were Irish Catholic, threw up a blockade from torn-up paving stones. Famously, the old ladies emptied their chamber pots on to the fascists from the upper windows.
This was the Battle of Cable Street. It stalled fascism in Britain for the rest of the century. Today we must show the same level of solidarity with people of all religions, and all ethnic groups. We must not wait for privileged people to take the lead in our political movements.
