New Delhi - Indian shares opened Wednesday with gains of over 4 per cent over its previous close, a day after Prime Minister Manmohan Singh won a trust vote in parliament ending weeks of uncertainty.

The 30-share Sensex of the Bombay Stock Exchange was trading at 14,733.86, up 629 points or 4.46 per cent at around noon, while the broader 50-share Nifty of the National Stock Exchange hovered around 4414.95 points or 4.12 per cent up on Tuesday's close.

Singh's United Progressive Alliance (UPA) government won the trust vote which came up after left parties allies withdrew support over a controversial civilian nuclear deal with the United States. The UPA won by a majority of 275 to 256 votes on Tuesday night, several hours after the markets closed.

Prospects of a stable government, lower global crude oil prices and positive cues from Asian markets all added to the positive mood in the markets on Wednesday, analysts said.

Indian Finance Minister P Chidambaram said there were several important financial bills pending and the government would attempt to push these through by reaching out to a wider section of lawmakers beyond those who supported the UPA in the trust vote on Tuesday.

The markets had been performing poorly over the past month due to rising crude oil prices, high inflation, political instability and the prospect of an early election if the government failed to win the trust motion.

The minority UPA government's term is scheduled to end in May 2009. (dpa)
