The Aam Aadmi Party and Congress on Tuesday filed a petition in the Punjab-Haryana High Court highlighting concerns over the integrity of the recently conducted mayoral elections in Chandigarh. The court will hear the matter on January 31. After BJP's Manoj Sonkar won the Chandigarh mayor election, a ruckus broke out in the House. Congress and AAP councillors accused the BJP of cheating and not following the due electoral process.
