Sources reveal the Thackeray cousins have taken step together to forge a new alliance in Mahrashtra.
Raj on Tuesday extended his support for Shiv Sena's mayoral candidate in the Thane civic corporation.
"I am fulfilling Balasaheb's (Sena patriarch) wish," he said.
Shiv Sena supremo, Bal Thackeray has of late been advising both the cousin to join hands together.
Uddhav also publicly pledged his support to the MNS and said, "Should Raj need Sena's support for winning Nashik corporation, we shall be right behind him."
"If the MNS and the Sena come to an agreement of supporting each other, it will spell doom for the Congress-NCP alliance, which is weakening across Maharashtra," said a political analyst.
