Pranab Mukherjee's sister Annapurna Banerjee on Saturday said it was a "time of immense happiness" for the family, a day after the name of the former president was announced for the coveted Bharat Ratna.
She said Mr Mukherjee's son Abhijit and daughter Sharmistha called her on Friday and conveyed the news.
"This is a time of immense happiness for me. He got what he deserved," the elder sister of the former president told reporters who visited their ancestral residence in Birbhum district.
"The whole family believes he got the honour he richly deserved," Ms Annapurna said.
The government had on Friday announced the country's highest civilian award for Mr Mukherjee for his contribution to public life.

"The Gandhi family had not deemed Mr Mukherjee fit for the honour (when they were at the helm)," he said.
