The speaker of DR Congo's Senate, Alexis Thambwe Mwamba, tendered his resignation on Friday, according to a letter seen by AFP, in the latest move to sideline allies of former president Joseph Kabila. In a letter to the Senate's supervisory bureau, Thambwe Mwaba said "trust no longer exists between a group of senators and myself," referring to plans by a majority of legislators to file a censure motion against him. His resignation is the latest in a string of top-level political departures following a tussle for power between supporters of Kabila and President Felix Tshisekedi, who succeeded the long-ruling leader in January 2019. mbb/bmb/blb/ri/dl
