The writing appeared to be on the wall for Shiv Sena (UBT) as six of its nine Lok Sabha MPs skipped its parliamentary party meeting here on Thursday, signalling that a formal crossover to the ruling Shiv Sena led by Eknath Shinde may be only a matter of time. Sena (UBT) MPs Arvind Sawant, Anil Desai and Rajabhau Waje attended the meeting, along with Sanjay Raut, the party's lone Rajya Sabha MP. The absence of the remaining six MPs all but confirmed a split in the party's parliamentary ranks.
