lk advani challenges manmohan singh to contest loksabha election

Lk Advani has challenged Congess PM Candidate Manmohan Singh to contest Lok sabha election.
LK advani said that Manmohan singh should contest lok sabha election , win the election and then look for becoming PM of India instead of becoming the Prime Minister as a member of the Rajya Sabha.

In reply to this , Congress said that , Indira Gandhi the 1st woman PM of India was Rajya Sabha Member when she became PM of India first time. Same is true for H.D. Deve Gowda. Hence is not against law.
