Assam CM Himanta Biswa Sarma has reiterated he has "solid evidence" proving that Assam Congress chief Gaurav Gogoi's UK-born wife Elizabeth Colebourn had links with Pakistan's ISI. "With full responsibility, I am saying...she is part of a cartel that helps Pakistan," he added. Referring to Gogoi, Sarma said, "After I reveal everything, that gentleman should disown his wife."
