Leaders of 14 political parties attended the event.
Nitish Kumar and Mulayam Singh Yadav shared the stage at a meeting organised by the Left in Delhi today, brought together by their fierce opposition to the BJP and its presumptive prime minister Narendra Modi.
Leaders of 14 political parties, including Mr Kumar's Janata Dal United and Mr Yadav's Samajwadi Party, attended the meeting fueling speculation about a possible re-grouping of a Third Front. Mr Kumar admitted there was much curiosity about this, but would only say, "We are here to fight communalism. Democratic forces should unite as much as possible to defeat fascist forces."
Mulayam Singh, who supports the Congress at the Centre but has in the past hinted at the possibility of bringing together non-Congress and non-BJP parties for a political alternative at the Centre, said, "A candidate from the Third Front will be the next Prime Minister. But it will be formed only after the 2014 elections."
The meeting was watched carefully for the political signals it sent.
One of the ruling Congress' closest allies, the Nationalist Congress Party attended, but its Praful Patel emphatically said there was no move to cobble together a third front.
It was the makings of anti-Modi front that many speeches seemed to reflect. Like Nitish Kumar, the SP and Left parties accuse the BJP and Mr Modi of "divisive politics."
"Narendra Modi says he is a Hindu nationalist. We cannot have a Hindu nationalist or Mulsim nationalist or Sikh nationalist. We want a secular nationalist," CPM leader Prakash Karat said.
Tamil Nadu Chief Minister J Jayalalithaa stayed away, but sent a senior colleague and a statement that said, "The State is often seen to be acceding to the pressure of both minority demands at one time and to majority demands at another, which has fuelled the activities of various groups. Secularism does not mean appeasing one section of society while suppressing the others."
Ms Jayalalithaa, who has in the past described Mr Modi as a good friend, did not meet him when he was in Chennai earlier this month.
Chandrababu Naidu of the Telugu Desam Party did not attend. Mr Naidu, a friend of the Left, has recently been seen as getting closer to the BJP.
