The Bharatiya Janata Party (BJP) on Monday swept the Mira-Bhayandar Municipal Corporation election in adjoining Thane district, winning 61 of the 95 seats.
While BJP secured a clear majority in the poll, Shiv Sena, its bickering ally in the state government, managed to win just 22 seats.

Maharashtra Chief Minister Devendra Fadnavis welcomed the results, saying it was a "Huge win for BJP."
"Now, development is certain. We will certainly live up to the expectations of people," he tweeted.
"Congratulations to leaders and karyakartas (workers) for spectacular win! I thank people of Mira-Bhayander for having faith in us! I assure speedy development," he said.
The election victory is because of wave of 'vishwas & vikas' created by PM Narendra Modi ji and team BJP's efforts!" he said.
