RJD MLA Sudhaker Singh, whose insolence had cost him his cabinet berth, on Saturday shot off an angry letter to Chief Minister Nitish Kumar alleging that the veteran leader had "lost trust of the people".The legislator, on whom the party had recently slapped a show cause notice but stopped short of disciplinary action, shared his letter, running into three pages, on social media.The first-term MLA appeared to have taken to heart the CM's assertion the day before that his outbursts over farmers' woes in Bihar betrayed ignorance of the government's achievements in agriculture, a portfolio he had held for barely a couple of months.
