Sheila Dikshit, who takes over as Delhi Congress chief from Ajay Maken, said today that there is "no talk of any alliance with the Aam Aadmi Party (AAP)" yet. "AAP and BJP both are an equal challenge to us, we will meet the challenges together," said the three-time chief minister. The 80-year-old indicated her objection to any truck with AAP which, she said, had spoken poorly of former prime minister Rajiv Gandhi during a discussion in the Delhi assembly.
