"When the entire nation is mourning those killed in the Kabul blast, the Left has chosen to make the announcement. It is most unfortunate. They think their prestige is more important than the nation's prestige," AICC media department chairman Veerappa Moily said minutes after the Left's announcement.

Party chief Sonia Gandhi not unaware of the Left's stance called an emergency meeting of senior leaders to take stock of the situation.

A meeting of the Cabinet Committee of Parliamentary Affairs (CCPA) is scheduled to be held this evening which will decide on the dates for the monsoon session of Parliament.

The CCPA meeting is being held amid reports that the Government could go in for a trust vote on July 28 during a special session.
