The bypolls were necessitated after Uttar Pradesh chief minister Yogi Adityanath and deputy chief minister Keshav Prasad Maurya vacated the Gorakhpur and Phulpur Lok Sabha seats following their election to the state legislative council. At the end of round 2, the SP took a lead of 1,500 votes, after which the SP kept on increasing its lead.
The Samajwadi Party has slipped into the lead as votes are counted in by-elections for Uttar Pradesh's Gorakhpur parliament seat, where a top official has barred the media from entering the counting centre in what is now a full-blown political controversy.
The elections see a triangular contest between the Bahujan Samaj Party (BSP)-backed Samajwadi Party, the Bharatiya Janata Party and the Congress which chose to fight the elections on its own.
Gorakhpur is significant for the BJP as it is the bastion of the chief minister, who represented the seat in the Lok Sabha five times.
An Election Commission (EC) official said all arrangements had been made for the counting of ballots and the results were expected to be declared by tomorrow afternoon.
In Phulpur, SP's Nagendra Pratap Singh Patel was ahead by 3,600 votes with BJP's Kaushalendra Singh Patel trailing behind him.
