Last year, a march there reportedly attracted fewer than 800 people, while official figures estimate 350 people took part. At least two other parallel Russian March parades were held in Moscow that day.
Gorsky said his group was in talks with other nationalist movements to hold the march together.
“Only one party is resisting,” he noted. “For some reason, it decided it has a monopoly on nationalism.”
Dmitry Dyomushkin, co-founder of the march, was sentenced to 2.5 years of prison on extremism charges earlier this year for sharing images on social networks.
