Prateek Yadav, the son of late Mulayam Singh Yadav, founder of the Samajwadi Party in India, is reported to have died of natural causes, according to sources from the post-mortem examination. The examination revealed no blue marks on his body, but a blue tint on his toenails has raised questions about possible underlying health issues. Yadav had been suffering from liver and lung complications and had been admitted to Medanta Hospital in Lucknow multiple times for his deteriorating health. Authorities have preserved his viscera for further analysis to determine the exact cause of death. His wife, Aparna Yadav, a leader of the Bharatiya Janata Party (BJP), was not present at the time of his hospitalization. Akhilesh Yadav, Yadav's half-brother and former Chief Minister of Uttar Pradesh, expressed his sorrow on social media, paying tribute to him. The final post-mortem report is expected to take several days to complete.
