The credibility of India’s polling monitor is under examination.

India’s Election Commission (ECI), one of the most trusted public institutions in the world’s largest democracy, is facing a test of its credibility.

Over the past few weeks, it has fielded a string of allegations from the opposition, ranging from voter fraud and manipulation to inconsistencies in electoral rolls. It has denied all of these.

Opposition leaders, who have held massive protests against the ECI in recent days, said they were considering an impeachment motion to remove the chief election commissioner from his position. They hadn’t filed the motion by Thursday, the last day of the monsoon session of parliament, and currently don’t have the numbers to see it through.
