On Tuesday, in a setback to the Congress and the AAP -- both partners in the opposition INDIA bloc -- the BJP swept the Chandigarh mayoral polls.
The AAP-Congress combine alleged that the presiding officer had tampered with the ballot papers.
Priyanka Kakkar, the AAP's chief national spokesperson said in a brief statement, "We have received news about the fifth summons. Our legal team is studying it and we will decide what to do as per law. The earlier summonses were illegal and we had sought a reply from the Enforcement Directorate."
