Greater Noida (Uttar Pradesh): Asserting that the BJP is going to retain power in 2019, Union Home Minister Rajnath Singh on Monday said the coming Lok Sabha election is not a challenge to the ruling party.

Attacking the opposition rally organised by West Bengal Chief Minister Mamata Banerjee, the Minister said the attempt to form a 'mahagatbandhan' showed how much the other parties feared the Bharatiya Janata Party.
