LONDON — Barclays said Sunday that its chief financial officer and its general counsel would resign, the latest departures after the British bank’s involvement in a series of scandals, including an investigation into the manipulation of global interest rates.

The announcement comes less than two weeks before Barclays is to announce a far-reaching overhaul of its business. The finance chief, Christopher G. Lucas, and the group general counsel, Mark Harding, will remain in their jobs until the bank appoints successors, Barclays said in a statement.
