Sheila Dikshit, three-time Delhi Chief Minister, is among the candidates the Congress named today for six of the seven seats in Delhi for the national election, signaling that a tie-up with Aam Aadmi Party is no longer on the table. The party has left out just one seat, South Delhi, where its planned candidate Ramesh Kumar, the brother of 1984 anti-Sikh riots accused Sajjan Kumar, has provoked anger from Sikh groups.
