The new government has set up a dedicated office for reconciliation under the Chair of 69-year-old Kumaratunga, the country's first woman president.
The Presidential Task Force on Reconciliation (PTFR) would identify urgent reconciliation needs that require immediate solutions. The PTFR would also consider proposals from citizens for the purpose.
Kumaratunga was the fifth President of Sri Lanka, who served from 1994 to 2005. In November last year Kumaratunga formally announced her return to active politics.
