With just 20 days to go for polling in the national capital, the suspense continues over Delhi's ruling Aam Aadmi Party (AAP) and the Congress on forming an alliance to take on the BJP.

While the AAP is also keen on a pre-poll alliance in Haryana, which will vote on May 12, the Congress is only willing to discuss a tie-up in Delhi. With both the parties sticking to their demands, the alliance issue in Delhi is in limbo.
