"BJP UP in charge Amit Shah was given permission to campaign but the ban on state Cabinet Minister Mohd Azam Khan continues, which was a clear sign of discrimination," addressing an election rally here Yadav said.
Yadav said there was a straight fight between SP and BJP in the Lok Sabha elections in Uttar Pradesh, and no government would be formed at the Centre without SP's support.
Claiming that SP fulfils its promises, Mulayam said if voted to power the party would provide employments to youths.
The Election Commission had ordered the UP government to ban Shah and UP minister Azam Khan from campaigning in the state following their controversial remarks on April 11.
Later, the EC had lifted its ban on Shah's participation in Lok Sabha poll campaign in Uttar Pradesh on April 17 after he assured the poll body that he would not disturb the public tranquillity and law and order.
