NEW DELHI — India's parliament was adjourned on the first day of a new session after opposition lawmakers demanded the resignation of leaders tainted by corruption allegations, deepening an impasse that has stalled the government's reform agenda. Members of the opposition Congress party on Tuesday stormed the well of the chamber in the upper house, shouting slogans and forcing the speaker to halt proceedings. The house was adjourned for the day after repeated protests. Prime Minister Narendra Modi appealed for the opposition to work with the government. “We want to take the country forward,” Modi said on his way into parliament. “I hope parliament will respect the country's aspirations.” In the monsoon sitting of parliament, the government's main goal is to ease the passage of the biggest overhaul of taxes since independence in 1947. All eyes are on the upper house, where the government and its allies are a minority. Passing the measure would be a victory for Modi and go some way to reassuring investors who are growing jittery that economic modernization is happening too slowly. Modi is under pressure from the opposition to fire his foreign minister and a state leader amid claims they gave favors to a sports tycoon living in London who faces allegations of tax evasion. Separately, the chief minister of a central Indian state governed by Modi's party is on the defensive over the deaths of witnesses involved in a massive fraud in entrance exams for college and government jobs. Modi has made tentative progress on economic transformation since he swept to office a year ago, and in his first year parliament was a third more productive than the first year of the last government, data by PRS Legislative Research shows. But the pace of change has been slower than many expected from the man some supporters cast in the mold of reformers such as Britain's Margaret Thatcher or China's Deng Xiaoping, and private companies are slow to invest in economic revival. Plans to pass a business-friendly land purchase law are on the backburner after Congress and other parties dubbed it “anti-farmer” and refused to let parliament vote on it. The tax bill has been passed in the lower house and got the support of an upper house panel on Monday. But the government needs a two-thirds majority to make it law, which it will struggle to reach without Congress support. Congress wants the bill to be amended before backing it. The lower house shut down for the day soon after reopening to allow lawmakers to mark the recent death of a member. The BJP does not have a majority in the upper house, and analysts say opposition parties will try to prevent progress in the current session, which comes ahead of elections in the eastern state of Bihar later this year. “This will be a very stormy session since the objective is no more to conduct parliamentary business, but to put the government in the dock,” said political analyst K.G. Suresh. Parliament's last session was the most productive in recent years, with 23 bills passed, including long-awaited legislation to open the insurance market to foreign companies. Voters turned against the Congress Party in general elections last year after it was embroiled in a string of corruption scandals during its decade in power. — Agencies
