Samajwadi Party chief Mulayam Singh Yadav has again raised the picth for a third front. Speaking at a rally in Etawah he said, 'Congress is an opportunist. Whenever elections are around the congress, they first waiver off loans but after coming to power they cheat the poor farmers. Congress is a party that betrays everyone.' But congress leader Digvijaya Singh played down Mulayam's remark by saying that he has the right to express his views.
