Terming the BJP's victory in Uttar Pradesh assembly polls as "unprecedented", party chief Amit Shah said the win is a stamp of approval on Prime Minister Narendra Modi's work.
Shah said the party would win the 2019 Lok Sabha poll with a bigger mandate than 2014.
"The victory is a stamp of approval on Prime Minister's work, " Shah said addressing party workers and supporters at the BJP's national headquarter at 11, Ashoka Road here.
"It is after a long time that a party is getting two - thirds majority in Uttar Pradesh.
This victory is unprecedented in many ways, " Shah said.
"After independence, Narendra Modi is the leader who has not just talked about the poor, but worked for them.
He is the most popular leader, " Shah added.
He said demonetisation, free cooking gas connections to the poor, mission on toilets under the Clean India programme and Jan Dhan accounts worked in favour of the BJP.
"This is two steps ahead of our victory of 2014.
In the coming days, we will also spread to eastern and western states.
We will get a bigger mandate in 2019 under the leadership of Narendra Modi, " he said.
