Mukul Roy passed away on February 23, 2026, at Apollo Hospital in Salt Lake, Kolkata, around 1:30 am. According to family sources, he died due to a massive cardiac arrest. His son, Subhranshu Roy, confirmed the news.
In recent years, Roy had been battling multiple health complications. He underwent brain surgery in 2023 for hydrocephalus. In July 2024, he suffered a head injury after a fall at home, leading to a blood clot that required surgery. Doctors had confirmed in early 2023 that he was suffering from dementia and Parkinson’s disease. He was also dealing with diabetes and other age-related ailments, which kept him away from active politics since 2022.
As per his latest election affidavit, his declared net worth was approximately 50.85 lakh rupees.
On the personal front, Roy came from a disciplined family background. His father, Hari Dev Kaushal, was a retired Assistant Commissioner of Police in Delhi, and his mother, Anup Kaushal, was a teacher. He was earlier married to Shilpa Dev, and the couple had a daughter, Sia or Siya Dev, before separating in 2005.
Mukul Roy’s death marks the end of a significant chapter in West Bengal politics. Despite political shifts and controversies, his role in reshaping the state’s political landscape remains undeniable.
