Prateek Yadav, the younger son of Mulayam Singh Yadav, founder of the Samajwadi Party, died on Wednesday morning in Lucknow, Uttar Pradesh, India, at the age of 38. Family sources reported that he was found lying in his kitchen and was rushed to a local hospital, where he was declared dead upon arrival. An autopsy indicated that the cause of death was cardiorespiratory collapse due to massive pulmonary thromboembolism, linked to his ongoing lung-related health issues. His wife, Aparna Bisht Yadav, who is currently the vice-chairperson of the Uttar Pradesh State Women Commission and a member of the Bharatiya Janata Party (BJP), was not present in Lucknow at the time of his passing but returned later in the day. Akhilesh Yadav, the president of the Samajwadi Party and Prateek's brother, was the first family member to arrive at the King George Medical College for the autopsy.
