Uddhav Thackeray, watching hordes of Shiv Sena leaders switching to the rival faction led by Maharashtra Chief Minister Eknath Shinde, will start losing his MPs soon. A dozen Shiv Sena MPs are in touch with Eknath Shinde and may form a separate group in the Lok Sabha, sources say. This coincides with the Chief Minister's visit to Delhi for discussions with the BJP leadership on the Maharashtra cabinet.
