New Delhi, April 27 -- Aam Aadmi Party MP Sanjay Singh said on Sunday that he has submitted a petition to Rajya Sabha Chairman C P Radhakrishnan seeking the disqualification of seven party MPs in the Upper House, who recently quit the AAP and announced their merger with the BJP. Addressing a press conference, the AAP Rajya Sabha member also said the party would pursue legal action in the matter if needed, alleging that the move by the seven MPs violated the anti-defection law. The AAP has urged the Rajya Sabha chairman to terminate the memberships of the seven MPs, claiming that they were elected to the Upper House on AAP tickets but later decided to leave the party and join the BJP. On Friday, the AAP suffered a jolt when seven of its Rajya Sabha MPs - Raghav Chadha, Ashok Mittal, Sandeep Pathak, Harbhajan Singh, Rajendra Gupta, Vikram Sahni and Swati Maliwal - quit and merged with the BJP, alleging that the Arvind Kejriwal-led party had strayed from its principles, values and core morals. "According to the Constitution, two-thirds of the total MPs of a party can merge with another party," Raghav Chadha had said, Singh asserted that Chadha and the others who left AAP for the BJP are likely to lose their Rajya Sabha memberships, as he believes no MLA would want to risk their future by aligning with them. "Would anyone wish to join him and risk their own membership being cancelled? Everyone understands this in politics," Singh remarked.P4...
