Modi faces revived opposition after setback in southern state

NEW DELHI: Indian opposition parties have joined forces to snatch power from the country's ruling party in a big southern state, laying the stage for other such alliances in a direct challenge to Prime Minister Narendra Modi's re-election bid next year.

A coalition of Congress and a regional group said on Sunday they will establish a government in Karnataka state next week, after Modi´s Bharatiya Janata Party (BJP) failed to prove its majority despite bagging more seats than any other party in a closely-fought election.

Rahul Gandhi, the leader of the Congress party - which has struggled to make any major political inroads since Modi stormed to power four years ago - said his party will rally regional groups into a common front against Modi. "I am very proud that the opposition has stood together and defeated the BJP, and we will continue to do so," said Gandhi.

Karnataka, with a population of 66 million, was the first major state this year to elect an assembly, and will be followed by three more before the general election in 2019.Political strategists say polls in Karnataka, home to India's "Silicon Valley" Bengaluru, which was previously known as Bangalore, were seen as a key test of Modi's popularity but the final outcome highlights the threats he faces from a united opposition are much bigger than anticipated.
