Interestingly, representatives from J Jayalalithaa's party AIADMK and Naveen Patnaik's Biju Janta Dal will also be attending the meeting along with leaders from CPI-M, CPI, JD(U), Samajwadi Party, and some parties from northeast.
BJP looks at AIADMK and BJD as its possible allies after next Lok Sabha polls.
JD(U) President Sharad Yadav, who along with Left has played a key role in organising the proposed 'Convention Against Communalism and For Unity of People', however, said that though this cannot be called any Third Front shaping up, the "effort is to bring all non-Congress non-BJP parties, who are against price rise and corruption of the present government."

He denied suggestions that JD(U), which had parted ways from BJP over projection of Narendra Modi, can come back to the NDA fold if Modi takes a back seat.
"All this is absurd. We parted ways on an issue of principle. It's a different matter, if they change their principles. They (BJP) do not say it but their purpose is to divide the nation. Ever since the NDA broke up the debate in the country has shifted to non-issues," he said.
