She also urged people to never forget the 'martyrs' of political violence during the Left front rule.
"On this day in 2006, Tapasi Malik was brutally raped and burnt to death in Singur. Let us also never forget the martyrs of the 34 years of violence under the Left Front," Banerjee wrote on her Twitter handle this morning.
Malik was a member of the Save Singur Farmland Committee. Her charred remains were recovered from the Tata Motors' Nano factory site in Singur on December 18, 2006.
The agitation that lasted for months made headlines across the world and catapulted then opposition leader Mamata Banerjee to limelight.
