Mullah Abdul Ghani Baradar is a Taliban co-founder.
He became a lynchpin of the insurgency after the militants were toppled by the US-led invasion in 2001.
But he was captured in a joint US-Pakistani operation in the southern Pakistani city of Karachi in February 2010.
He remained in prison for eight years, until he was released as part of a plan to facilitate the peace process. He has been the head of their political office in Qatar since January 2019.
In 2020, Baradar became the first Taliban leader to communicate directly with a US president after having a telephone conversation with Donald Trump. Before that, Baradar signed the Doha agreement on the withdrawal of US troops on behalf of the Taliban.
