Indian Prime Minister Narendra Modi̵
The BJP focused heavily on West Bengal during the campaign, but was comfortably held by current Mama Banerjee, a fierce critic of Modi.
The party held power in Assam, but failed to make big profits elsewhere.
The vote was closely watched for signs of a reaction against Mr Modi amid the crisis in India in Kovid.
For 10 consecutive days, daily deaths have exceeded 300,000. On Sunday, India set a new record for daily deaths with 3,689 recorded. Hospitals face acute shortages of beds and medical oxygen, with many Indians resorting to desperate pleas on social media for help.
Campaign rallies and voting have been blamed for the jump in cases.
What happened in Bengal?
With almost all the results counted, Mama Banerjee’s Trinamool Congress (TMC) party has more than 200 seats in the 294-seat assembly.
The results are set to make Ms. Banerjee the leader of West Bengal for the third time. She is also the only woman prime minister in India.
Celebrating the victory, she said West Bengal had “saved” India with the result. “This is the victory of the people of Bengal, the victory of democracy,” she told her supporters.
The victory was exacerbated by the loss of her place in Nandigram to a former assistant who became a BJP deserter. She said she would challenge the outcome in court, but may have to run again to remain chief minister.
West Bengal, home to 90 million people, is of particular interest to election observers. This is one of the few countries where Mr Modi does not have a majority of parliamentary seats and has never been ruled by his Hindu nationalist party, the BJP.
Despite the defeat, this vote saw the BJP win nearly 80 seats to become the main opposition party in West Bengal. In the 2016 vote, the party won only three seats.
How about another place?
In addition to the northeastern states of West Bengal and Assam, there are voting in the southern states of Tamil Nadu and Kerala, the southern Indian provincial province of Puducherry, and local council elections in parts of Uttar Pradesh and Telangana.
In Tamil Nadu, the main regional opposition party, the DMK, took power. Their leader, MK Stalin, was named in honor of the late Soviet dictator.
The left-wing coalition retained power in Kerala until a BJP-led alliance won seats.
In addition to the coronavirus pandemic, some analysts see the results as showing the limits of BJP’s Hindu rhetoric in countries with significant Muslim populations.
