Meetings with Lok Sabha speaker
On June 17, Shrikant Shinde and Omraje Nimbalkar met Speaker Om Birla early in the morning.
Later, the remaining five rebel MPs also met the Speaker and submitted a letter outlining their decision.
In the letter, the MPs stated that they intended to merge with the Eknath Shinde-led Shiv Sena and sought a change in their seating arrangement in the Lok Sabha.
The rebel group consists of six of Shiv Sena UBT's nine Lok Sabha MPs, giving it the two-thirds strength generally required to avoid disqualification under anti-defection provisions.
The meeting with the Speaker is being viewed as a significant step in formalising the latest split within the Thackeray camp.

Thackeray camp responds
The Uddhav Thackeray-led faction has reacted strongly to the rebellion.
Party leaders have reportedly issued seven-day show-cause notices to the six MPs and urged the Speaker not to accept their demands regarding separation from the party and changes in seating arrangements.
The party has also indicated that the MPs could face internal disciplinary proceedings for alleged anti-party activities.
Tensions escalated further after the six MPs reportedly ignored a party whip directing them to attend a meeting.

Sanjay Raut levels serious allegations
Shiv Sena UBT leader Sanjay Raut intensified the political confrontation during a press conference, alleging that the rebellion had been orchestrated through what he described as "Operation Tiger".
Raut claimed that rebel MPs were flown to Delhi in chartered aircraft and alleged that large financial inducements had been offered to encourage them to switch sides.
He alleged that "Rs 15 crore" had been paid in advance and claimed that the rebel MPs would collectively receive "Rs 50 crore" for defecting from the party.
The allegations have not been independently verified.

Echoes of 2022 Shiv Sena split
The latest developments have revived memories of the 2022 political upheaval in Maharashtra when Eknath Shinde led a rebellion involving 40 of the Shiv Sena's 55 MLAs, resulting in the collapse of the Maha Vikas Aghadi government and Uddhav Thackeray's resignation as Chief Minister.
With six of the party's nine Lok Sabha MPs now seeking alignment with the Shinde faction, the latest revolt threatens to further weaken the Thackeray-led camp while strengthening Eknath Shinde's position within the Shiv Sena.
