The Shiv Sena (UBT) has issued a whip to its MPs to attend a meeting in New Delhi to discuss “important issues”, amid the speculation of an imminent rebellion in the Uddhav Thackeray-led party, sources said on Wednesday.The party can initiate disqualification proceedings against those who skip the meeting, they said.The party had issued a similar whip when 39 MLAs led by Maharashtra Deputy Chief Minister Eknath Shinde rebelled against the Sena leadership in 2022, following which disqualification proceedings were initiated against them.The Opposition Shiv Sena (UBT) is staring at a crisis, with “six to seven” of its nine Lok Sabha MPs inclined to switch to the Shinde-led ruling Shiv Sena and camping in the national capital, sources said on Tuesday.
