A case has been registered against Samajwadi Party (SP) Uttar Pradesh president Akhilesh Yadav (also known as Mulayam Singh Yadav's son and heir apparent) and 35 of his partymen for allegedly violating the model code of conduct, police said. 

Akhilesh addressed party workers while on way to Siddharth Nagar from Sharavasti last night without permission, District Magistrate Sunita Chaturvedi said.

An FIR has been lodged against Yadav and 35 SP party workers, she said.

Yesterday, the Election Commission issued a notice to Congress leader and Union Minister Salman Khurshid for violating the model code of conduct by promising nine per cent sub-quota for backward Muslims in Uttar Pradesh if voted to power.
