Tight security arrangements have been made with almost 6,500 personnel of central armed para-military forces deployed, apart from Provincial Armed Constabulary (PAC) and homeguards to ensure peaceful polling in Gorakhpur and Phulpur seats, vacated by Adityanath and Deputy Chief Minister Keshav Prasad Maurya respectively following their election to Uttar Pradesh Legislative Council.
The intensity of campaigns by Yogi and Maurya is an evidence that the elections will be hard fought since the two powerful regional outfits SP and BSP joined hands to take on the saffron brigade.
U.P. Deputy Chief Minister Keshav Prasad Maurya said the 2014 Lok Sabha record would be repeated by the BJP.
According to the Election Commission, 19.61 lakh electorate in Phulpur Lok Sabha constituency is expected to exercise their franchise at 2,059 polling booths, while 19.49 lakh electorate in Gorakhpur Lok Sabha constituency is expected to cast vote at 2,141 polling booths.
Much is at stake both for the ruling party and the Opposition as the prestigious Gorakhpur and Phulpur seats go to poll on Sunday.
Peace Party, NCP, Rashtriya Lok Dal and some other smaller parties have also declared their support for SP candidates in both constituencies.
The BJP has fielded Kaushalendra Singh Patel from Phulpur and Upendra Dutt Shukla from Gorakhpur against the SP's Pravin Nishad and Nagendra Pratap Singh Patel respectively.
The ruling BJP did not only win both the seats in the 2014 general election but also swept the state Assembly polls a year ago.
The death of RJD MLA Mundrika Singh Yadav necessitated the bypoll for Jehanabad seat, and his son Uday Yadav is contesting for the seat. The contest is mainly between the late RJD MP's son Sarfaraz Alam and BJP's Pradip Singh.
The Bhabua assembly seat got vacant after the death of BJP's Anand Bhushan Pandey, and the party has fielded his widow Rinki Rani Pandey. Another key candidate in the fray is JDU's Abhiram Sharma. Mr. Adityanath had to vacate his Gorakhpur Lok Sabha seat.
The poll results will come out on Mar 14.
