He also accused the government of wanting to continue the standoff so that issues of critical concern to the people are not taken up.
Mr Sharma alleged that the government does not want the opposition to raise issues of acts of "commission and omission" and the wrong decisions of the prime minister.
He said that the government does not want that it is exposed on the floor of the House on issues such as the Rafale deal which the opposition wants to discuss.
"It is the responsibility of the PM to clear doubts regarding his accusations. It is his duty to restore the dignity of the office and in the interest of parliamentary democracy that this deadlock comes to an end," Mr Sharma told reporters.
"We urge the prime minister to shed his 'raaj-hatth' (stubbornness) and clarify his remarks against (Manmohan) Singh and (Hamid) Ansari, which he made to win Gujarat polls," Mr Sharma said.
The stalemate, he said, continues primarily because of the attitude of the government and obduracy of the prime minister, who refuses to register the seriousness of the situation resulting from his "baseless and unwarranted aspersions" for electoral gains.
