"Show cause notices have been served to former MLA Ram Iqbal Singh and Babban Singh Raghuvanshi while 12 leaders have been expelled from the party by state president Laxmikant Bajpai," a senior party leader said here.
The action was taken for anti-party activities after the leaders allegedly attacked party MP Maurya on January 4 when he was here for organisational elections, he said.
Those expelled included two district vice presidents, a district secretary besides others.
On January 4, when the MP visited the district BJP office for organisational elections, these party men allegedly attacked him and also damaged his vehicle.
