DMK annouced it will vote in favour of the UPA government on FDI issue in Parliament during voting.
"DMK took the decision with "bitterness" to prevent communal forces from coming to power, party chief Karunanidhi said.
Earlier, main oppositon party BJP on Tuesday said it will insist on discussion on FDI in retail issue under rules which entail voting and asked the government to give up its "adamant" attitude and "allow the House to function" by agreeing to the Opposition demand.
"Government has not kept its assurance to Parliament that the decision on FDI will be taken only after discussing the issue with all stakeholders. The sense of the House on the issue can be known only through voting. So, the government should give up its adamant attitude," BJP spokesperson Shahnawaz Hussain said.
He maintained that the government is responsible for Parliament not functioning as it is not agreeing to voting and discussion on the FDI issue.
"Government should not show arrogance of power and agree to the opposition demand. BJP and NDA are not ready for anything less than voting and discussion. We want a debate only under Rule 184," Hussain said.
Party leaders indicated that BJP and its allies will not allow Parliament to function till the government accedes to its demand.
