Yadav, whose party has given a notice to Lok Sabha Speaker Meira Kumar seeking permission to raise the issue in House during the upcoming session, thanked Trinamool Congress chief Mamata Banerjee for halting the move on FDI earlier.
Raising the banner of opposition, Samajwadi Party yesterday joined hands with Left parties and JD(S) asking the government not to go ahead with the controversial decision without wide-ranging consensus.
SP chief Mulayam Singh Yadav, CPI(M) General Secretary Prakash Karat, CPI General Secretary S Sudhakar Reddy, Forward Bloc's Debabrata Biswas, JD-S' Danish Ali and RSP's Abani Roy wrote a joint letter to Prime Minister Manmohan Singh, saying parties across the spectrum are opposed to this move.
The JD-U chief said he thanked SP, CPI-M, JDS and RSP for opposing FDI in retail, saying "they have rightly done so. This move will be the biggest assault on Indian economy."
"We appeal to all parties including the UPA allies to oppose this anti-people measure. A population of 22 crore Indians are employed in retail who will be affected by this attempt of the government, in a similar manner like the entry of East India company had destroyed India's trade," Yadav said.
Congratulating Banerjee for opposition to FDI in past, he said, "Mamata Banerjee was the only ally in UPA who opposed it and ensured that there was no move forward on it."
