New Delhi, Aug 7 : Left parties today staged a protest in Parliament complex over alleged attacks on opposition parties in West Bengal by ruling Trinamool Congress, which said it reflected their “frustation” at their “marginalisation” in the state.

Holding placards saying ‘Save democracy in Bengal’ and ‘Stop attacks on women and SCs/STs’ in the state, members of CPI(M), CPI, RSP and Forward Bloc staged a noisy demonstration at the main gate of Parliament.

When Lok Sabha assembled, the slogan-shouting members stormed the Well over the issue, which led to three adjournments. In Rajya Sabha, Left members including Sitaram Yechury tried to raise the issue amidst din.
