Punjab Congress chief Amarinder Singh on Tuesday said that the result of the Delhi municipal bye-elections was a reflection of poor performance of the AAP government in the city state."The bye-elections may have been held for 13 wards only, the results are certainly indicators of the popular sentiment in Delhi, which is clearly against the AAP. "Of the 13 municipal wards, AAP lost in eight, thus reflecting the popular disillusionment with the Kejriwal government in Delhi within a year," Amarinder said at a meeting of Congress leadership here.He said that the AAP bubble has already burst in Punjab with the vertical division in the party.The former chief minister also accused the AAP of having a "subtle understanding" with the ruling Shiromani Akali Dal in Punjab.Referring to Monday's AAP protest against Chief Minister Parkash Singh Badal, Amarinder said: "They (Akalis and AAP) are only playing a friendly match as they were feeling threatened by the Congress. The Akali Dal is deliberately trying to promote AAP in the hope of dividing anti-incumbency vote, which will otherwise straightway go to the Congress."
