He recalled that when he was the President of the BJP in the eighties, she was a promising young activist who he had inducted into the team.

"And over the years, she became one of the most popular and prominent leaders of our party -- in fact, a role model for women leaders," he said in a statement.

He said he is deeply distressed at the "untimely demise of one of my closest colleagues, Sushma Swaraj".

Advani called her a brilliant orator.

"I was often amazed at her ability to recall incidents, events and present them with utmost clarity and eloquence."

He said she was also a fine human being and touched everyone with her warmth and compassionate nature.

"I do not recall a single year when she missed bringing my favourite chocolate cake to me on my birthday," said Advani.

Expressing condolences, he added the nation has lost a remarkable leader.

"To me, it is an irrepairable loss and I will miss Sushmaji's presence immensely. May her soul rest in peace," he added.
