Congress President Rahul Gandhi on Monday said the party would form government in Delhi in the next assembly polls and took potshots at Aam Aadmi Party convenor Arvind Kejriwal, saying he should rather contemplate who lied about the Congress in 2014 and "opened the doors" for the BJP.Gandhi, who was addressing a public rally in Sadar under the Chandni Chowk Lok Sabha seat while campaigning for party candidate J.P. Agarwal, sought to explain his stance about not having an alliance with AAP. "I told him (Kejriwal) we should win all the seven seats in Delhi. I asked him to take four seats, while the Congress will contest the rest. First, he said 'okay'. As soon as I had approved of it, he brought in Haryana and Punjab in the picture," Gandhi said, adding that's when the alliance talks broke down."Kejriwal should reflect as to who opened the doors for BJP in 2015, who told lies about the Congress? It was not BJP alone," said the Congress President.He asked people to see for themselves as to which party is giving a tough fight to the BJP across the country."We, the Congress, have fought Modi wherever he has gone. We defeated him in several states. If any party in India can stop the BJP, it is Congress. It is a fight of ideologies. I tell u with guarantee that the Congress will defeat the BJP," Gandhi said.The seven constituencies in Delhi will vote on May 12. The BJP had bagged all the seven Lok Sabah seats in the 2014 elections.
