On 10th April 1848 the Chartists held a rally for the vote on Kennington Common. They had mostly marched from north of the river. The plan was to take a huge petition for the vote to Parliament. However once the Chartists had passed south the police and soldiers blocked them.
A leader of left Chartism, George Julian Harney who worked with Marx and Engels, made his position on this clear at a Chartist delegate meeting on 11th April.:
‘He would never again consent to leave London to hold a meeting
Northern Star 15th April 1848
Excellent !
I am just about to move to Newport Wales the home of Chartism. Newport Rising have done some excellent research on Chartism. I thoroughly recommend going to the Chartist march in November.
