Modi's ruling Party BJP voted out in key Indian state of Karnataka
India’s opposition Congress party has won power in a key state, partial election results showed, defeating Premier Narendra Modi's ruling Bharatiya Janata Party (BJP) a year ahead of national polls.
It removed Modi's ruling Party from office in Karnataka, the only southern state controlled by the Hindu nationalist grouping.
Karnataka has a population of more than 60 million people - about the same as the United Kingdom - and its capital Bengaluru is India's largest tech hub. The state voted on Wednesday and full results are expected later Saturday.
It is the second state Modi's party has lost to the Congress party in the previous six months. In December, Congress unseated Bharatiya Janata Party in northern Himachal Pradesh, a small state tucked in the Himalayas.
The poll results are expected to energise the largely divided opposition that is banking on forming a united front to challenge PM Modi in next year's general election, in which he will seek to extend his prime ministership for a third consecutive term.
