Rampur: ED (Enforcement Directorate) has summoned Samajwadi Party leader Azam Khan, his wife and son to its regional office in UP's Lucknow on different dates before July 15, in connection with a case linked to the construction of Mohammad Ali Jauhar University, Rampur.

The ED had already questioned several times Azam Khan while he was lodged in Sitapur jail.

However no one knows the outcome of those rounds of questioning. Is there really a merit in the case against SP leader  or it is just political vendetta?
