It's a hat-trick for Nitish Kumar as the JDU-RJD-Congress coalition of Grand Alliance has recorded a landslide victory in the Bihar assembly elections.

The Grand Alliance was poised to sweep a whopping 178 of the 243 seats, leaving the BJP -- which wanted to oust Nitish Kumar -- and its allies with just 58 seats.

That is, the Grand Alliance has notched up a two-thirds majority in the Bihar Assembly, a result that is the exact opposite of BJP president Amit Shah's claim made before the elections that his party would get a two-thirds majority.

Among the Mahagathbandhan allies, Janata Dal-United won 71 seats, Rashtriya Janata Dal 80 seats and Congress 27.

On the other hand the Bharatiya Janata Party could only win 53 seats, while its allies were reduced to one or two seats each. The Lok Jan Shakti Party of Ram Vilas Paswan and Rashtriya Lok Samta Party won two seats each, while Hindustani Awam Morcha secured one seat.

Interestingly, the Communist Party of India-Marxist-Leninist-Liberation won 3 seats, while Independents won 4 seats.
