“I am sorry to know about the sad demise of Kulsoom Nawaz. My heartfelt condolences to the bereaved family. May her soul rest in peace,” Sushma Swaraj tweeted.
Sushma Swaraj is known to have been personally close to the Sharif family. In the Heart of Asia Summit in 2015 in Pakistan, she met the four generations of the Sharif family.
Kulsoom Nawaz passed away in a hospital in London on Tuesday after battling with cancer for months, the family said.
She is survived by her husband and four grown-up children — Hassan, Hussain, Maryam and Asma.
Nawaz Shairf and Maryam are currently serving a jail sentence at Adiala Jail in Rawalpindi for corruption.
