A group of men and women in yellow T-shirts and saris accompanied Gopal Italia, the Gujarat unit chief of the Aam Aadmi Party (AAP), as he went from door to door in Tribhuvan Nagar of Surat. The former police officer and leader of the Patidar movement sought votes from the residents of the influential “Diamond Constituency” of Katargam, renowned for trade in the precious stone, while promising jobs and free electricity. People of the state want ‘parivartan’ (change), he said, and the AAP was here to deliver it.
