NEW DELHI - India’s ruling Congress party failed to make a breakthrough in recent elections in the politically crucial state of Uttar Pradesh, according to voter surveys published on Sunday. Congress, which has struggled to implement planned reforms since it held onto power in the 2009 general election, campaigned hard in a state that is seen as a key pointer towards the next national poll due by 2014. Several voter surveys put the Congress party, which leads a fractious coalition in New Delhi, in fourth position after the staggered elections in the northern state of Uttar Pradesh ended on Saturday.
