BJP Kerala unit president Kummanam Rajasekharan on Friday filed an election petition before the High Court challenging the election of Congress candidate K Muraleedharan from Vattiyoorkavu constituency in the recent Assembly polls.

In his petition, Rajasekharan contended that Muraleedharan did not declare his assets and liabilities fully before the returning officer.

He said the "returning officer has improperly accepted" the nomination of Muraleedharan in spite of the fact that the petitioner's authorised agent has pointed out before the returning officer while scrutinising his nomination that he has "suppressed his assets and liabilities".

The suppression amounts to corrupt practise, the BJP leader alleged while seeking to set aside the election of Muraleedharan.
