AAP's Gurgaon candidate Yogendra Yadav was Wednesday served a show cause notice by the Election Commission for having political offices at two places without permission.
Assistant Returning Officer Vivek Kalia served the notice that said that Yadav's offices were based at Sohna and Tauru, an official said.
Yadav has been asked to explain by 11.30 a.m. Friday why action should not be taken against him for violating the code of conduct.
