Opposition parties on Tuesday submitted a notice to move a motion for removing Vice President Jagdeep Dhankhar for allegedly conducting the House in a partisan manner.
Congress leaders Jairam Ramesh and Naseer Hussain submitted the notice to Rajya Sabha Secretary General P C Mody.
The vice president is the ex-officio chairman of Rajya Sabha.
The sources said about 60 opposition MPs — including from the Congress, RJD, TMC, CPI, CPI-M, JMM, AAP, DMK — have signed the notice.
However, they said top Congress leaders who hold Constitutional posts have not signed the notice.
