Communist Party of India (Marxist) general secretary Sitaram Yechury, on Sunday, alleged that BJP-led Union government is posing a grave threat to federal structure.

Participating in the conference, ‘Protect Constitution’, here on Sunday, Yechury said, by introducing GST, the Centre had snatched the right to collect tax from the state governments. Though the states have freedom to decide on cattle trade, the prime minister has taken a unilateral decision on the Bill.

Yechury said, BJP,  a political weapon of RSS, has been blatantly violating the provisions of the Indian Constitution. Independence, equality and brotherhood are under threat. Attack on Dalits, deprived classes and minorities has increased after BJP came to power.

Modi had assured farmers of waiving loans and announcing minimum support price for agricultural produce ahead of Lok Sabha elections in 2014. But he failed to keep his words,  CPM Politburo member said.
