Passage: After the capital moved from Calcutta to Delhi, the Viceroy occupied the newly built Viceroy's House, designed by Sir Edwin Lutyens. Though construction began in 1912, it did not conclude until 1929; the palace was not formally inaugurated until 1931. The final cost exceeded £877,000 (over £35,000,000 in modern terms) – more than twice the figure originally allocated. Today the residence, now known by the Hindi name of 'Rashtrapati Bhavan', is used by the President of India.

Question: Who uses the Rashtrapati Bhavan?
