Kuldeep passed his class 12 exams from Raja Shankar Sahay Inter College in Unnao. He started his political career with the Congress and became the pradhan of Makhi village in Unnao in 1997-98.

In 2002, he contested assembly elections as a Bahujan Samaj Party (BSP) candidate from Unnao Sadar constituency and won. Next time around, in 2007, he joined the Samajwadi Party (SP) and won from Bangarmau assembly seat.

Kuldeep again changed his seat to Bhagwant Nagar in Unnao in 2012 and contested the election as a Samajwadi Party candidate.

Before the 2017 assembly election, he joined the BJP and once again won from the Bangarmau seat.

The BJP fielded senior leader Hriday Narayan Dixit from Bhagwant Nagar seat.

He’s also brought in his family into politics. His brother Manoj Sengar has won a local-level election. Kuldeep’s wife Sangeeta Sengar was elected chairperson of the Unnao zila panchayat during the SP regime, a position she still holds.

“Kuldeep has positioned himself a prominent Thakur leader in Brahmin-dominated Unnao. He has a good hold on Muslim votes and also enjoys the support of other upper castes. He has considerable support among lower caste voters too. His formula to win the election is high social presence,” said Unnao-based political analyst Shailendra Shukla said.

While Kuldeep is a full-time politician, his brothers Manoj and Atul work to maintain his image of a ‘bahubali’ leader. Both Manoj and Atul have criminal cases against them.

The family also runs jewellery businesses in Unnao and Kanpur.

“His family is feared in the region because of Manoj and Atul, who manage the muscle and money power of the family,” said a police officer posted in Unnao.
