"We have expelled the six MPs for defying the party directive. We will inform the Speaker about our decision tomorrow," SP General Secretary Amar Singh told reporters here.
The MPs who are expelled from the party are Jai Prakash (Mohanlalganj), S P Singh Baghel (Jalesar), Raj Narain Budholia (Hamirpur), Afzal Ansari (Ghazipur), Ateq Ahmed (Phulpur) and Munnawar Hussain (Muzaffarnagar).
Singh also rubbished allegations that he paid money to MPs to defect and vote in favour of the Government.
"We also lost MPs. We have not paid money to anybody," he said.
