The BJP is "misusing" the ED to stop Delhi Chief Minister Arvind Kejriwal from campaigning for Lok Sabha polls, Environment Minister Gopal Rai said after the probe agency sent its fourth summons to the AAP chief on Saturday.

Addressing a press conference, Rai questioned the timing of the Enforcement Directorate's summons to Kejriwal, saying it came ahead of his Goa tour from January 18.
