Why is Chandrika Kumaratunga considered as a great leader in Sri Lanka?

Both the parents of Chandrika Kumaratunga served as prime ministers of Sri Lanka – her father Solomon Bandaranaike and her mother, Sirimavo Bandaranaike. Her husband, Vijaya Kumaratunga, with whom she had co-founded the Sri Lanka Mahajana Party, was assassinated. In August 1994, she became the Prime Minister. She took the presidency as well three months later in a separate election. She stood for the elections again in 1999. A suicide bomber made a bid on her life just days before the polling. Kumaratunga lost sight in one eye but won 51% of the vote to be elected for a second term.
