Shiv Sena (UBT) chief Uddhav Thackeray will not switch to the ruling BJP-led NDA, Maharashtra NCP (Sharadchandra Pawar) president Jayant Patil asserted on Thursday, seeking to scotch speculation about a possible crossover by his key ally. The Shiv Sena (UBT) won nine Lok Sabha seats in Maharashtra in the just concluded elections, the same as the BJP, while its rival faction led by Chief Minister Eknath Shinde bagged seven.
