Signalling its keenness to create a third "alternative" along with the UNPA, Left parties on Thursday announced that they would coordinate with the alliance against the government over the Indo-US nuclear deal and other issues.The Left, which provide crucial outside support to the ruling UPA, dropped hints of its intention to stitch a non-Congress and non-BJP alliance after UNPA Chairperson Mulayam Singh met CPI(M) General Secretary Prakash Karat and his CPI counterpart A B Bardhan here.After his meeting with Singh, Bardhan announced that the Left and the UNPA would jointly hold rallies in New Delhi on October 30 and in Vijayawada on November 24."On people's issues, we are on the same platform. There is an effort to create an alternative (to Congress and BJP) to raise people's issues and it will be formed," Bardhan told reporters along with Mulayam Singh.Asked whether the Left and the UNPA could formally come together, Singh said, "One cannot predict the result of joint struggles".Bardhan said the Left and the UNPA will "coordinate our stand in Parliament" on the Indo-US nuclear deal as both are opposed to the agreement.While the Left is asking the government to put on hold the deal, Singh went a step ahead and asked the government to scrap the agreement with the US as it poses a "big danger" to the country's sovereignty.On the issue of the nuclear deal, "we (Left and the UNPA) have the same opinion. We will fight together on this issue and will take it to the people," Singh said.Samajwadi Party leader Ram Gopal Yadav and TDP's Yerran Naidu will attend the farmer's rally to be held in the capital later this month, while Left leaders will participate in the rally organised by the UNPA in Vijayawada, Bardhan said.Talking to reporters, Samajwadi Party General Secretary Amar Singh came down heavily on senior Congress leader Veerappa Moily for dubbing the Left parleys with the UNPA as a "desperate measure"."Those who live in glass houses should not throw stones at others," Singh said, adding it was not surprising to hear such comments from "power brokers and sycophants and "we don't take it seriously".He said the Samajwadi Party and the Left have always been together on issues concerning the common man and there was nothing new in the parleys.
