The Congress will speak to Bihar Chief Minister Nitish Kumar and Telugu Desam Party chief Chandrababu Naidu -- both erstwhile allies -- to explore options for government formation, senior leaders of the party said today. INDIA bloc ally Uddhav Thackeray was the first to go public, saying the Congress intends to talk to both leaders. Senior Congress leader Salman Khurshid was more circumspect. "We will work towards getting all alliance partners and other to form a stable government," he said. The possibility opens up due to the narrow gap between the projected numbers of the NDA and the INDIA bloc.
