In May, Pol Pot adopted the Silver Pagoda as his main residence. He then relocated to the city's tallest structure, the 1960s-built Bank Buildings, which became known as "K1". Several other senior government figures—Nuon Chea, Sary, and Vorn Vet—also lived there. Pol Pot's wife, whose schizophrenia had worsened, was sent to live in a house in Boeung Keng Kâng. Later in 1975, Pol Pot also took Ponnary's old family home in the rue Docteur Hahn as a residence, and subsequently also took a villa in the south of the city for his own. To give his government a greater appearance of legitimacy, Pol Pot organised a parliamentary election, although there was only one candidate in every constituency except in Phnom Penh. The parliament then met for only three hours.
