Modi led the BJP in the 2014 general election, which gave the party a majority in the Lok Sabha, the first time a single party had achieved this since 1984. Modi himself was elected to parliament from Varanasi. Since taking office, Modi's administration has tried to raise foreign direct investment in the Indian economy, increased spending on infrastructure, and reduced spending on healthcare and social welfare programmes. Modi has attempted to improve efficiency in the bureaucracy, and centralised power by abolishing the planning commission and replacing it with the NITI Aayog. He has begun a high-profile sanitation campaign, and weakened or abolished environmental and labour laws. Credited with engineering a political realignment towards right-wing politics, Modi remains a figure of controversy domestically and internationally over his Hindu nationalist beliefs and his role during the 2002 Gujarat riots, cited as evidence of an exclusionary social agenda.
