TUNIS (Reuters) -A Tunisian judge on Thursday sentenced opposition leader Rached Ghannouchi, a fierce critic of President Kais Saied, to three year in prison on charges of accepting external financing, his lawyer Monia Bouali told Reuters. Ghannouchi, 82, head of the Ennahda main opposition party, has been in prison since April. Last year he was sentenced to a year in prison on charges of incitement against police.
