Shiv Sena (Uddhav Balasaheb Thackeray) (ISO: Śiva Sēnā (Uddhava Bāḷāsāhēba Ṭhākare); lit.

SS (UBT))[9][10][11][12] is a Hindutva-based, Marathi regionalist,[13][5] nationalist political party formed in 2022 under the leadership of former Chief Minister of Maharashtra, Uddhav Thackeray.

It was one of two separate factions, the other being the Balasahebanchi Shiv Sena, led by Eknath Shinde, formed as a result of the 2022 Maharashtra political crisis, until the Election Commission recognised the faction led by Eknath Shinde as the legitimate structure of Shiv Sena in February 2023.

On 17 February 2023, Election Commission of India recognised Eknath Shinde's faction as representing Shiv Sena officially.

[17] While both parties said that they have come together to "save constitution and fight for regional pride", political analysts pointed out several contradictions in their positions on various core issues.
