The controversy about super stores has become a political storm in parliament.

On Tuesday, opposition lawmakers stalled the legislature for a second day, with the issue.

Sushma Swaraj, the leader of the opposition Bharatiya Janata Party, insists that the government reverse the decision to open the retail sector to foreign investors. Swaraj is angry that the government did not take all political parties on board before announcing the landmark reform.

At least two political allies of the government are also demanding its rollback.

Several states ruled by opposition parties have already announced that they will block the entry of foreign super stores. They include Tamil Nadu, Bihar, Kerala, Uttar Pradesh and West Bengal, a state ruled by an ally of the ruling Congress Party.

Backers of the plan say the government went forward, despite the opposition, because it wanted to address concerns that the pace of economic reforms has flagged and it wanted to rejuvenate an economy which is slowing after years of high growth.

The government insists that foreign stores will bring in much-needed investment to build supply chains and cold storage facilities, improve farmers’ incomes, create millions of jobs and make food cheaper.

The so-called organized retail sector is at a nascent early stage in India, with a handful of domestic companies accounting for a mere six percent of India’s $450 billion retail sector.
