Region warns Niger's leader on plan to keep power
* Economic sanctions plus AU measures threatened
* Niger ECOWAS membership could be suspended
* Opposition calling for resistance to referendum
NIAMEY, May 18 (Reuters) - Niger's neighbours could penalise it with economic sanctions if President Mamadou Tandja's plan to stand for a third term contravenes pledges to follow democratic principles, regional body ECOWAS said on Monday.
The government announced this month the 70-year-old leader, whose second and final term expires this year, would hold a plebiscite on constitutional changes to allow him to run again in polls due in November. The move sparked a street protest and opposition anger in the uranium-mining state.
