Indian Prime Minister Narendra Modi has expanded his Cabinet and council of ministers in a bid to boost the government's agenda and kick-start the economy.

Twenty-one new ministers took the oath of office at a ceremony Sunday at the presidential palace in New Delhi.

The portfolios of the new ministers and the reshuffle of the ministries held by other Cabinet and council members were not announced immediately.

Modi, who took office in May after sweeping to power with a massive mandate in elections, now heads a 66-member council of ministers, with 27 of the ministers holding Cabinet rank.

Notable among the new Cabinet ministers is Manohar Parrikar, who resigned Saturday as the chief minister of the state of Goa in western India.
