NDTV's opinion poll shows the Narendra Modi-led BJP clawing its way back in Delhi after a decade.
The BJP, which had drawn a blank in 2009 and could win only one seat in 2004, is expected to win four of the seven seats in the capital.
The Congress is expected to retain only one seat; the party had swept all seven seats in the 2009 election. In the December assembly polls, the party suffered a humiliating defeat, placing third after the BJP and debutant Aam Aadmi Party of Arvind Kejriwal.
Mr Kejriwal's party is expected to win two parliamentary seats, extending its impressive run since the assembly election. The poll shows the voters' enthusiasm for the party has ebbed a little after its 49-day stint at ruling Delhi, but AAP is confident of proving its critics wrong.
