The Congress on Friday came down heavily on Leader of the Opposition Lal Kishenchand Advani for demanding a trust vote in Parliament.

"No one has withdrawn support from the government as of now. So where is the question of trust vote?" said Congress spokesman Manish Tiwary.

He charged Advani of making an irresponsible statement when the prime minister is going for the G-8 summit in Japan [Images].

"Why is Advani creating an instability with such demands?" asked Tiwary.

"There is no instability in the government and politics in the country. If there is any instability it is in the mind of the leader of the opposition," he said.

"The nuclear deal is an issue of national importance and getting energy and any party which supports us is welcome," he said dismissing charges of political opportunism levelled against his party.
