The BDP runs in the family tree

President Ian Khama succeed his father, Sir Seretse Khama who was the founding leader. When he was the MP for Serowe North West, Khama was not challenged in the BDP primaries. His younger brother, Tshekedi Khama succeeded his older brother in Serowe North West. 

Tshekedi was not challenged in the BDP primaries. BDP youth leader, Gomolemo Motswaledi dared to challenge Tshekedi but was warned to back off. Ian hinted a long time ago that Tshekedi would succeed him.
