The Enforcement Directorate has issued sixth summons to Delhi chief minister Arvind Kejriwal in the alleged Excise Policy Scam case. The central probe agency has asked Mr Kejriwal to appear before it on 19th of this month. AAP Convenor has already missed all five previous summons by the ED. Last week, Delhi's Rouse Avenue court also summoned Mr Kejriwal on seventeenth of this month, after the ED had filed a complaint against the Delhi chief minister as he skipped all the summons.<br />
