Odisha Chief Minister Naveen Patnaik and Telangana CM KC Rao will meet West Bengal CM Mamata Banerjee in Kolkata on Monday.
On Sunday, Rao met Patnaik and emphasised a "dire need" for unification of regional parties to provide an alternative to the Congress and the BJP ahead of the Lok Sabha elections 2019.

The meeting between the two leaders assumed significance amid talks about efforts on formation of a new political front of like-minded, non-BJP and non-Congress parties to take on the national ones in the upcoming polls.
"I can say certainly that there is a dire need for unification of regional parties in the country. We strongly believe that there has to be an alternative to the Congress and the BJP," Rao told reporters after meeting BJD president and Odisha Chief Minister Naveen Patnaik.

Both the chief ministers had a detailed discussion on national issues, including the need for "better friendship among regional parties", Patnaik said.
"This is just the beginning of a dialogue... We will meet again and discuss how to take things forward," Rao said.
After an impressive victory of the Telangana Rashtra Samithi (TRS) in the state assembly poll, Rao has embarked on a journey to bring together anti-Congress and anti-BJP parties for next year's Lok Sabha polls.
While Prime Minister Narendra Modi goes to Hyderabad and says the TRS is the "B team" of the Congress, its president Rahul Gandhi claim that the TRS president is the "B team" of the BJP, Rao said, adding, "Let me tell you, we are our own team."
Senior Congress leader and the party in-charge for Telangana, Ramachandra Khuntia, alleged that Rao's meeting with Patnaik is part of a game plan to weaken the proposed "Mahagathbandhan" (grand alliance) among non-BJP parties.
The Telangana CM has been acting at the behest of the saffron party and the NDA to dilute efforts of like-minded, non-BJP parties for formation of a grand alliance before the general elections, Khuntia claimed.
Union Minister Dharmendra Pradhan said Rao's visit will have no impact on the BJP's electoral prospects as "zero added to zero will have no value".
