Former Madhya Pradesh minister Rajkumar Patel has been expelled from the Congress party for six years for allegedly giving a walkover to Bharatiya Janata Party (BJP) leader Sushma Swaraj during the recently held parliamentary elections, party sources said on Wednesday.

Patel was fielded against Swaraj on the Vidisha Lok Sabha seat but his nomination was rejected since he had submitted a photocopy of the Form-A (meant to inform the Election Commission of the candidate's party affiliation) whereas the rules categorically specify that the form has to be original.
