Seeking an explanation from actor Dharmendra for not mentioning his wife's name in the nomination filed by him for Bikaner Lok Sabha seat, the Congress Saturday said the Election Commission should immediately look into it.

"It is a serious matter. Dharmendra has given a wrong statement in his nomination papers," party spokesman Kapil Sibal told reporters in New Delhi.

The Bharatiya Janata Party should be held accountable for fielding Dharmendra who has claimed to marry two women, Prakash Kaur and Ayesha Bi (Hema Malini), the actress and BJP Rajya Sabha MP, Sibal said.

Dharmendra gave details of assets owned by him and his wife in the nomination papers but did not mention her name leaving a question mark if the assets were of his first wife or the second, he said.
