Attacking the National Democratic  for its boycott of Parliament, Congress President Sonia Gandhi [Images] on Saturday said it had not played the role of a responsible opposition, but evinced satisfaction over the government's performance
given the "compulsions" of a coalition.

"The opposition is not playing a constructive role and they are not working sincerely though they talk big things. They boycotted the session (of Parliament) and did not behave like a responsible opposition," the UPA Chairperson
said in Jind, Haryana.

"Despite this, we will not allow any weakness to creep in when it comes to implementing our policies and programmes," she said, addressing a "Dhanyavad Rally" to thank the people of Haryana for returning to power after nearly a decade with an overwhelming majority in the February 3 assembly elections.

In a broadside attack on the Bharatiya Janata Party, Gandhi said, "Our opponents used to say the Congress could not form a government at the Centre...we not only did that, but showed them we could run it smoothly".

She said there were the "compulsions of a coalition government", but expressed satisfaction at the way the UPA regime had been functioning over the past one year.

"The UPA government headed by (Prime Minister) Dr Manmohan Singh [Images] has almost completed one year in office and we have implemented several schemes for the welfare of the masses," Gandhi said.
