Ten Congress councillors from Jalandhar joined the AAP, with Punjab Chief Minister Bhagwant Mann formally inducting and welcoming them into the party fold, it said on October 14.
The move comes ahead of next month's municipal corporation elections in Jalandhar.
Elections to five municipal corporations in Punjab— Amritsar, Ludhiana, Jalandhar, Patiala and Phagwara— will be held within the first fortnight of November.
