"We have a group in discussions with the police over where the demonstration can be held," said Ammar Khorshed at the Line 17 neighbourhood association which is behind the demo.
Over 13,000 people have signed up for the demonstration which was organized in response to last Sunday's gathering which was attacked by a group of neo-Nazis from the national socialist Swedish Resistance Movement (Svenska Motståndsrörelsen, SMR).
"There are many who have said that they are going to show support and solidarity with our work, but it's hard to say how many we really will be. You should not have to feel afraid or limited in taking a stand against racism," Khorshed said.
Among those planning to attend are Social Democrat party leader Stefan Löfven and senior party member Veronica Palm.
Three people have been held on remand
on suspicion of violent rioting (våldsamt upplopp) after taking part in last Sunday's neo-Nazi attack on the peaceful demonstration. Twenty-six people were originally held after the clash.
The Swedish Resistance Movement has claimed responsibility for the attack involving around 30 neo-Nazis armed with fireworks, glass bottles, and sticks but were ultimately forced to retreat and flee.
The first of the men to be held on remand, Emil Hagberg, is believed to have been among the leaders of the attack, which saw three people rushed to hospital, including one police officer. Two of his accomplices, aged 23 and 24, were still being interrogated late on Wednesday afternoon.
Stockholm police, meanwhile, have organized raids on several of the homes belonging to those involved in the fracas.
