Modi led the BJP in the 2014 general election which gave the party a majority in the Indian lower house of parliament, the Lok Sabha, the first time for any single party since 1984. Modi's administration has tried to raise foreign direct investment in the Indian economy and reduced spending on healthcare and social welfare programmes. Modi has attempted to improve efficiency in the bureaucracy; he has centralised power by abolishing the Planning Commission. He began a high-profile sanitation campaign, initiated a controversial demonetisation of high-denomination banknotes and weakened or abolished environmental and labour laws.
