NATO Deputy Secretary-General Mircea Geoana announced on September 3 his resignation from that alliance post to run in Romania's presidential election in November. Geoana said he met with NATO Secretary-General Jens Stoltenberg the same day to inform him of his plans. Geoana and other NATO sources confirmed the information to RFE/RL's Romanian Service. Geoana will reportedly be replaced in the deputy's post by German Boris Ruge. Stoltenberg is due to be succeeded by former Dutch Prime Minister Mark Ruttee on October 1. Current Romanian President Klaus Iohannis is barred from a third term by Romania's constitution.
