Indian government loses majority as Trinamool party leaves alliance

India's government lost its majority yesterday when a key ally finalised its divorce from the coalition, but it was saved from the immediate risk of collapse by securing the support of a regional party.

Six ministers from the regional Trinamool party handed in their resignations to the prime minister and president, in response to a series of controversial economic reforms rolled out in the past week.

All 19 Trinamool lawmakers will now join the opposition ranks, ending an uneasy alliance inside the left-leaning coalition and leaving Prime Minister Dr Manmohan Singh's Congress party dependent on outside support from other parties in parliament.

The Congress party has received backing from the Samajwadi Party from Uttar Pradesh state, whose 21 members have generally backed the government and who have vowed to prevent the opposition Hindu nationalist Bharatiya Janata Party from taking power.

Years of tension between Congress and Trinamool exploded last week after Singh's government announced a string of reforms, including allowing foreign supermarkets into the retail sector and increasing the price of subsidised diesel.

Fiery Trinamool chief Mamata Banerjee initially gave the government 72 hours to withdraw the reforms, then said on Tuesday that her party would quit unless her demands were met.
