Prime Minister Narendra Modi on Monday expressed confidence that the NDA will get more than 400 seats and the BJP will win at least 370 seats in the Lok Sabha elections.

Modi said he was convinced that the opposition parties have lost the courage to contest elections and have resolved to stay on the opposition benches for a long time.

"I can gauge the mood of the nation, it will definitely give NDA more than 400 seats and the BJP at least 370 seats," the prime minister said replying to the debate in Lok Sabha on the Motion of Thanks on President's Address.

He said the third term of the government was not too far.

"At the most 100-125 days are remaining," he said, referring to the upcoming Lok Sabha elections. "Abki baar," Modi said, and BJP members joined him in unison to say "400 paar".

"Even Kharge ji is saying the same thing," Modi said referring to Congress President Mallikarjun Kharge's statement in Rajya Sabha.

He said the NDA's third term would be the one that would see big decisions and lay the foundation for the next 1,000 years.

Prime Minister Modi tore into the Congress, attacking it on the issue of dynastic politics and saying it had a good opportunity to play a good opposition but failed in that role.

He said some opposition leaders were keen to change their parliamentary seats, while some others were planning to move to Rajya Sabha.

"I appreciate the resolution the Opposition has taken. Every word of their speeches has confirmed my confidence and that of the country that they have resolved to stay there (in the opposition) for a long time," Modi said and blamed the Congress for the opposition's present condition.

"For several decades you were sitting here (in the treasury benches), but now you have resolved to stay there (opposition benches) for several decades.

"The people will bless you and keep you there. You will achieve greater heights and will be soon seen in the public galleries (of the House)," the prime minister said.

Modi said that the Budget Session was a good opportunity to make some constructive suggestions, but the opposition members have let go of a good chance.

"You have left the country disillusioned... Leaders have changed but the same tune continues," he said.

The opposition could have given some message to the people in an election year, Modi said, adding that the Congress was responsible for the present state of the opposition.

"Congress had a good opportunity to play a good opposition but failed in that role. There are other young people in the opposition, but they were not allowed to speak out of fear that it may overshadow a particular person," Modi said in an apparent reference to Rahul Gandhi.

The prime minister said the Congress may soon have to "shut shop" due to its attempt to launch the same product time and again.

"It's election time, and you should have worked a bit harder, brought something new and sent a message to the people. However, you failed miserably. Let me teach you this very thing.

"The Congress party is responsible for the current condition of the opposition. The Congress got an opportunity to become a good opposition. However, they failed to fulfil their responsibility in the last ten years...," Modi said in Lok Sabha.
