Who stands where: Political composition of new Lok Sabha

The treasury benches in the new Lok Sabha, with a greater BJP presence than in 2014, will have a sizable number of MPs from states like West Bengal, Odisha, Telangana, Assam and Tripura.

This is in keeping with the saffron party's expanding footprint across the country.

The BJP has won a lion's share of 303 seats out of a total of 542 at the cost of regional players like the Trinamool Congress, the Biju Janata Dal and the Telangana Rashtra Samiti, thereby bringing about a marked change in the opposition benches.

The BJP has dented the Trinamool's parliamentary presence by winning 18 seats from West Bengal, an increase of 16 seats compared to 2014. Mamata Banerjee's party, on the other hand, has been reduced to 22 in the lower house, 12 less than last time. The Biju Janata Dal would have a somewhat shrunken presence with 12 MPs. The Odisha party had 20 MPs in the previous Lok Sabha.

The TRS won nine seats, two less than last time, while the BJP got a surprise haul of four from the southern state.

The BJP's Uttar Pradesh presence, however, is marginally diminished, with the party winning 62 seats in the electorally crucial state, compared to the mammoth haul of 73 in 2014. Among the notables who won from UP are Prime Minister Narendra Modi himself and Union ministers Rajnath Singh, Maneka Gandhi, Satyapal Singh and Smriti Irani. Irani enters the Lok Sabha with the repute of being a giant killer on account of having defeated Congress president Rahul Gandhi in Amethi. Also getting elected to the Lok Sabha is Rita Bahuguna Joshi, who was formerly the president of the UP Congress. However, Union minister Manoj Sinha lost from Ghazipur.

Though the regional parties in UP—the BSP and the SP—could not contain the BJP, they have increased their Lok Sabha numbers at 10 and six, respectively. However, the Yadav family will be represented only by Mulayam and Akhilesh, with their kin, including Akhilesh's wife Dimple, losing.

The Congress has increased its numbers only marginally, from 44 in 2014 to 52 now. However, it is a much depleted force with many of its stalwarts and notable members losing, including Mallikarjun Kharge, who was the Congress's leader in the Lok Sabha, Jyotiraditya Scindia, who was the party's number two in the lower house, M. Veerappa Moily, Ashok Chavan, Sushmita Dev and Ranjeet Ranjan. While UPA chairperson Sonia Gandhi would be the party's sole representative from UP, Rahul will be there as the MP from Wayanad in Kerala.

In fact, the Congress benches will have a substantial presence from the south, having won 15 seats in Kerala and eight in Tamil Nadu. The other sizable chunk of the Congress Legislature Party will be from Punjab, where the party won eight seats.

After the Congress, the DMK, with 23 seats, is the third largest party in the Lok Sabha. The Tamil Nadu party is also the only UPA ally with numbers in the double digits. Another staunch ally, Lalu Prasad's RJD, failed to open its account. Former NDA ally, TDP, which had worked actively to bring about the opposition unity, is a much reduced force at three MPs. The party had 15 MPs in the previous Lok Sabha. TDP rival, YSR Congress, now has 22 MPs in the lower house. On the other hand, NDA ally JD(U), which had fought the 2014 general elections separately, winning just two seats then, now has 16 MPs. Another NDA ally, the AIADMK, which was the third largest party in the previous Lok Sabha, has managed to win just two seats.

The Left's presence has been reduced to just five. The Left parties had ten MPs in the previous Lok Sabha.

The new entrants of the BJP include party president Amit Shah and Union minister Ravi Shankar Prasad.
