"I'll not be able to make it to the PM function in Patna and Hajipur on March 12 due to personal and unavoidable reasons," Sinha told PTI here over phone.
Sinha's elder brother Bharat Sinha's former wife Sheela Sinha was yesterday found hanging at her residence in Gurgaon. She had been separated from Bharat, a London-based doctor, for the past 25 years.
"The entire family is drowned in sorrow over the incident and due to the tragedy, I will not be able to come for the function," Sinha, BJP Lok Sabha member from Patna Sahib, said.
The Patna High Court falls under Parliamentary constituency of Sinha.
Sinha's name was prominent in the advertisement given by the East Central Railway (ECR) regarding its function.
