Lawyers, retired judges and former police officers here have formed a forum to launch a signature campaign against the candidature of actor-turned-politician Sanjay Dutt, who is a Samajwadi Party Lok Sabha candidate from Lucknow.

"With signatures of the residents of Lucknow, we will send a memorandum to the Chief Justice of India (CJI), requesting him to turn down Dutt's plea to contest the polls," Rajiv Hemkeshav, convener of the newly constituted Forum Against Criminalisation of Politics said.
