BRASILIA (Reuters) - A harsh critic of President Michel Temer in Brazil's Senate quit the leadership of the ruling party on Wednesday, exposing a rift within Temer's coalition but suggesting the president retained enough support for a key vote on a labour overhaul.
Senator Renan Calheiros announced his resignation as party leader saying that, unlike most of his party members, he could not give his backing to proposals that hurt Brazilian workers, especially if they came from a president lacking credibility in the middle of a corruption scandal.
