"The BJP government at the Centre is trying to curb the democratic rights of the country. We protest against the attack on the higher educational institutions by BJP and RSS. We also condemned the arrest of Kanhaiya Kumar," West Bengal Left Front Chairman Biman Bose said.
Bose also questioned the silence of Trinamool Congress over the JNU row.
The protesters marched for about 3 kms from Curzon Park in central part of the city and ended the rally at the historic Mahajati Sadan.
