The pointed remark came a day after conclusion of the two-day BJP national executive meeting here which re-elected Gadkari as the party president for the second term.
"Under your leadership, BJP has miserably failed to play its role as a responsible opposition party," Maharashtra Pradesh Congress Committee (MPCC) spokesperson Sachin Sawant said in a letter to BJP president Nitin Gadkari.
Accusing BJP of being "power hungry" in his letter, Sawant said,"to achieve the objective, BJP is attempting to create unrest and doubts against the government by painting an exaggerated picture which is far from reality. Such attempts may give you (BJP) temporary satisfaction. But, the party's credibility does not improve".
"The country is passing through difficult economic situation. Such crises exists in countries in Europe as well as the USA....Everybody there came together to strengthen the hands of the heads of the government to overcome the crises. Unfortunately, this does not happen in India," Sawant said.
He further said that BJP's opposition to UPA policies revolved around the fact that it does not want Congress to succeed even if national interest is not served.
Without taking names, the spokesperson said, "there is still two years time for the general elections but the struggle for PM's post has begun in your party".
