Congress today downplayed the contention that attempts by regional parties and the Left to cobble together a Third Front will seal the prospects of a Congress-led secular alliance saying "possibilities change in politics with the passage of time".        

Party spokesperson Randip Surjewala said, "Politics is an expression of possibilities and the possibilities change with the passage of time. Let us wait for a while."        

His remarks came on a day when 11 non-Congress and non-BJP parties formally joined hands as a block in Parliament to pitch for pro-people, anti-communal and federal agenda.        

The announcement of the front was made at a joint press conference of leaders of these parties including the four Left parties, Samajwadi Party, JD(U), AIADMK, AGP, Jharkhand Vikas Morcha, JD(S) and BJD.
