The Rajya Sabha has been adjourned till 11 am on Thursday. Earlier, the Upper House of the Parliament was adjourned three times in a day following a ruckus created by the Opposition over the suspension of 12 MPs.
The winter session of Parliament began on November 29 and will continue till December 23.
Twelve Opposition MPs -- six from the Congress, two each from the Trinamool Congress and Shiv Sena, and one each from the CPI and CPI(M) - are holding an indefinite protest since they were suspended last week for the entire Winter Session of Parliament for their "unruly" conduct in the previous session in August.
The suspension of the MPs has led to disruption of proceedings in the Upper House, which did not carry any significant business for the second consecutive day on Tuesday.
