“Samajwadi Party president Mulayam Singh Yadav should have taken his MPs into confidence but he chose otherwise following which I boycotted today’s meeting in New Delhi,” Mohanlalganj MP Jai Prakash Rawat told reporters in Lucknow.

Claiming about 12 MPs, including some who attended Tuesday’s meeting, were also against the nuclear deal, Rawat said in case of trial of strength he would defy party whip.

“Though several MPs are in touch with each other over the issue I can speak for myself and I will defy the whip,” Rawat said.

Last week party MP from Muzaffarnagar Munawwar Hasan had come out openly against the deal and echoed similar views.

Stressing he would oppose the party decision within the organisation in a democratic manner, he said as of now he had no plans of quitting the party. He, however, did not rule out the possibility of revolt in the party over the issue.

“The party leadership should have convened a meeting of MPs and apprised them of the details,” he said.

Claiming more voices of dissent would emerge in the SP soon, he said as the nuclear deal is against national interest he would continue his opposition at every level.
