“Those expelled included former MLA Raghuvir Singh, Lakhan Singh and village head of Naraura, Pappu Diwakar,” party spokesman Rajendra Chowdhury said.
SP is fighting indiscipline in its ranks since the time it came to power. In a month it has fired several party leaders for indiscipline and anti-party activities.
Etah, from where SP started its Assembly poll campaign, is a strong hold of the party and hometown of its supremo Mulayam Singh Yadav.
On March 21, Mulayam had talked tough to the party leaders and asked them to keep their supporters “in control”.
