New Delhi, Dec 1 (IANS): Both houses of parliament were adjourned till noon Thursday following protests by opposition members against the decision to permit foreign investment in retail and Kerala MPs demanding a new dam instead of the Mullaperiyar dam.

As soon as Speaker Meira Kumar tried to initiate Question Hour in the Lok Sabha after an obituary reference and a resolution on World AIDS Day, opposition members stood up and shouted slogans demanding a rollback of the decision on foreign direct investment in multi-brand and single-brand retail.

Several MPs moved towards the speaker's podium. MPs from Kerala, belonging to both the Congress and the opposition, held up placards demanding the construction of a new dam in place of the 116-year-old Mullaperiyar dam.

As the ruckus continued, the speaker adjourned the Lok Sabha till noon.

Similar protests marked the beginning of the day in the Rajya Sabha with Chairman Hamid Ansari adjourning the upper house till 12 noon as the clamour over protests on FDI and the Mullaperiyar dam continued.

This is the fourth successive day of logjam in parliament over the FDI issue. In fact, no substantial business has been done in the winter session of the parliament, which began Nov 22, because of adjournments over price rise, FDI, Telangana and other issues.
