NCP president Sharad Pawar on Wednesday made a fresh pitch for the unity of opposition parties to take on the BJP after meeting West Bengal Chief Minister Mamata Banerjee here.

Banerjee, notably, made a cryptic remark that there was "no UPA" now.

The Trinamool Congress supremo paid a visit to Pawar on Wednesday after meeting Shiv Sena leaders the day before.

"All those opposed to the BJP are welcome to join us. There is no question of excluding anyone," Pawar told reporters when asked if an alliance without Congress was on the cards.

"We discussed the prevailing situation and the need for all like-minded parties to come together and provide a strong alternative to the BJP," the NCP chief said.

"Leadership is not an issue at this point. We need to unitedly work against the BJP," he added.

When asked if she wanted Pawar to be the chairperson of the Congress-led United Progressive Alliance (UPA), Banerjee said, "Three is no UPA now."

Earlier on Tuesday, Mamata had met Shiv Sena leaders Aaditya Thackeray and Sanjay Raut.

The meeting was seen as an outreach to fellow Opposition leaders by the Trinamool Congress supremo.

Mamata was scheduled to meet Chief Minister Uddhav Thackeray earlier, but as he is unwell, she met his son and minister Aaditya Thackeray, sources said.

Aaditya also gave her a copy of a coffee-table book of his father's photographs, sources added.

Earlier in the day, Mamata visited the famous Siddhi Vinayak temple here.

The West Bengal Chief Minister also paid her respects at the memorial of police constable Tukaram Ombale who died fighting terrorists during the 2008 Mumbai terror attack.
