Karnataka Chief Minister Siddaramaiah’s son, Rakesh Siddaramaiah, died yesterday of multi-organ failure at a Belgium hospital, where he was undergoing treatment, official sources said.

Rakesh, aged 39, was admitted to Antwerp University Hospital in Brussels on Tuesday after he developed sudden pancreas-related complications.

He had been on a European tour with his friends since last week.

Rakesh, the eldest son of Siddaramaiah, who had an acute pancreatic ailment for long, was critical but stable before his condition worsened, the sources said.

“Rakesh died of multi-organ failure,” the Chief Minister’s Office said.

Siddaramaiah, his wife and second son Yathindra Siddaramaiah, a doctor, and the family doctor were in Brussels to be with Rakesh.

He is survived by his wife, a son and daughter.

He had met with an accident 15 years ago, when he suffered injuries to his pancreas.
