Prime Minister Rajiv Gandhi, whose Congress (I) party was humiliated in a state assembly election in southern India Monday, bounced back Tuesday with convincing wins in two northeastern states.

In Nagaland, on the Burmese border, Congress had won 31 of the 52 seats declared with seven more results to come. In nearby Mizoram, the nationally ruling party had captured 22 of the 39 seats declared with only one more result to come.Santosh Mohan Dev, Congress campaign manager in both states, portrayed the victories as a personal triumph for Gandhi.
