The Enforcement Directorate has deferred by a day to July 26 the summons issued to Congress President Sonia Gandhi for her questioning in the National Herald newspaper-linked money-laundering case, officials said.

They said she is now required to appear before the federal agency on Tuesday, and not on Monday (July 25). The reason for the change of date could not be ascertained immediately. Gandhi, 75, was questioned for over two hours during her first day of questioning in the case on July 21.
