Prateek Yadav, step-son of late Samajwadi Party patriarch Mulayam Singh Yadav, died in Lucknow on Wednesday morning, officials said.

Prateek, 38, was the half-brother of former UP president Akhilesh Yadav and husband of BJP leader Aparna Yadav.
According to Civil Hospital Director Dr G P Gupta, information about Prateek’s deteriorating health was received around 5 am, following which a medical team was rushed to his home in Gomti Nagar. “When the doctors reached there, his condition appeared to be critical. He was taken to the hospital and was declared dead at 5.55 am,” Dr Gupta said.

Since the exact cause of death could not be determined immediately, doctors conducted a post-mortem examination at King George’s Medical University, Lucknow, and the body was taken to Aparna’s house for further rituals, hospital officials said.
The autopsy report attributed Pratik’s death to “cardiac and respiratory collapse due to massive pulmonary thromboembolism,” indicating that a large blood clot severely obstructed blood flow in the lungs and caused sudden cardiac and respiratory failure. The report said the entire heart and viscera were preserved for chemical analysis.

According to people familiar with his medical history, Yadav had pulmonary embolisms, high blood pressure, anxiety-related illnesses and recurring heart problems, leading to frequent short-term hospitalizations and constant medical monitoring. He was last admitted to Medanta Hospital on April 29.
Pratik was the husband of BJP leader Aparna Yadav and had largely stayed away from active politics despite belonging to one of the most prominent political families in Uttar Pradesh. He was the half-brother of Samajwadi Party president Akhilesh Yadav.
Aparna Yadav is the vice-chairman of the state women’s commission.
“Prateik Yadav had a known case of hypertension and deep vein thrombosis and was visiting Medanta Lucknow for treatment. He was last seen on April 29, 2026,” Medanta Hospital said in a statement.
Akhilesh Yadav expressed his grief over the death of his half-brother. In a post on X, Akhilesh said, “Prateik always wanted to move forward in life through his hard work and remained health conscious since childhood.”
He said that he met Prateek about two months ago and advised him to take care of his health and focus on expanding his business.
Uttar Pradesh Chief Minister Yogi Adityanath visited Aparna’s house and offered his condolences to the family. “My condolences to the bereaved family. I pray to Lord Shri Ram that the departed soul attains eternal peace and that the bereaved family is given the strength to bear this immense grief. Om Shanti!” Adityanath said in a post on X.
