AAP 'fall' in Delhi
In Delhi, the opinion poll has predicted a sharp fall in the vote share of giant-killer Aam Aadmi Party (AAP).
The ABP News-Nielsen opinion poll – conducted between March 9 and 16, 2014 – predicted a vote share of 34 per cent in the elections, a drastic fall from 55% vote share it was expected to win in an earlier opinion poll conducted in January this year.
The results of the latest opinion poll, released on Saturday, said the 34 per cent vote share would translate into 3 seats in the Lok Sabha elections in Delhi.
Delhi has seven Lok Sabha seats which will go to the polls in the third phase on April 10.
AAP chief convenor Arvind Kejriwal, who formed a minority government in Delhi after a stupendous showing in the first elections the party contested, resigned on February 14 after failing to table its pet anti-corruption legislation, the janlokpal bill, in the assembly.
In the assembly elections held in December, the AAP had bagged 28 seats out of the 70 while the BJP and SAD alliance had won 32. The Congress came a distant third with just 8 seats but supported the AAP government from outside.
The ABP News-Nielsen opinion poll predicted the Congress to gain from the AAP loss, improving its vote share to 28 per cent from the 14 per cent predicted by opinion polls in February.
The BJP is also likely to get stronger with 32 per cent vote share and garner 3 seats, the opinion poll results showed.
As per the ABP News-Nielsen opinion poll, the BJP is "emerging stronger" as its vote share increased from 30 per cent and 1 seat, according to February opinion polls and 29 per cent share, according to January opinion polls.
The poll, which interviewed 456 respondents, gave a margin of error in the ranges of ±5%.
