MUMBAI: Shiv Sena (UBT) chief Uddhav Thackeray and Maharashtra Navnirman Sena (MNS) boss Raj Thackeray on Wednesday announced the alliance of their parties ahead of the January 15 Brihanmumbai Municipal Corporation (BMC) elections, putting months of speculation to rest.

Addressing a joint news conference with Raj, Uddhav said the two parties have come together to stay together. Raj, however, did not share details of the seat sharing between the two parties for the high-stakes BMC elections.

"Mumbai's mayor will be Marathi and will be ours," Raj said.

Uddhav said the parties have finalised their seat sharing for the Nashik Municipal Corporation where elections are due on January 15, along with Mumbai and 27 other municipal corporations in the state.

Talks are underway for an alliance between the two parties in other civic bodies, he added.

"Those who can't bear to see what is happening in BJP can also come with us," Uddhav said.
