KINSHASA (Reuters) - Congolese President Joseph Kabila will step down after elections held before the end of 2017, under a deal struck by political parties on Friday, according to a lead mediator from the Catholic Church.

Under the deal, Kabila will be unable to change the constitution to extend his mandate and run for a third term, Marcel Utembi, president of the Catholic Bishops’ Conference in the Democratic Republic of Congo, told reporters.
