What has been Shiv Sena's history of splits and defections?

Shiv Sena(UBT), formed in 2022 after Eknath Shinde's revolt split the undivided Shiv Sena, is again facing a rebellion, with six MPs likely to switch sides. The undivided party had broken its alliance with BJP in 2019 to form government with NCP and Congress. It has seen major turmoils over the years, including Uddhav's cousin Raj Thackeray's exit in 2005.
