Lee Hsien Loong. Neither the prime minister nor members of the cabinet are elected by parliament. The prime minister is appointed by the president, then Cabinet members, also known as ministers, are appointed by the president on the advice of the prime minister. The cabinet in Singapore collectively decides the government's policies and has influence over lawmaking by introducing bills. Ministers in Singapore are the highest paid politicians in the world, receiving a 60% salary raise in 2007 and as a result Prime Minister Lee Hsien Loong's pay jumped to S$3.1 million, five times the US$400,000 earned by US President Barack Obama. Although there was a public outcry regarding the high salary in comparison to the size of the country governed, the government's firm stance was that this raise was required to ensure the continued efficiency and corruption-free status of Singapore's "world-class" government. On 21 May 2011, following the 2011 general election, the Prime Minister announced that a committee would be appointed to review politicians' remuneration, and that revised salaries would take effect from that date. Legislative Parliament The unicameral Singaporean parliament is the legislature in Singapore with the president as its head. Before independence in 1965, it was known as the Legislative Assembly. It currently consists of 93 members of parliament. The maximum term of any one parliament is five years, after which a general election must be held within three months of the dissolution of parliament. The 93 elected members of parliament (MPs) are elected on a plurality voting basis and represent either single-member constituencies (SMCs) or group representation constituencies (GRCs). In GRCs, political parties field a team of between three and six candidates. At least one candidate in the team must belong to a minority race. Formerly, there were no GRCs, and all constituencies of Singapore were represented by one member, but amendments to the Parliamentary Elections Act in 1991 led to the creation of GRCs, thus creating a plurality voting system in the process. This development has led to complaints from opposition parties that they are often unable to field one, let alone three or more candidates. Out of the 93 members of parliament, 26 are female. In the 2001 and 2006 general election, the incumbent People's Action Party (PAP) won the same configuration of 82 out of the 84 seats. The final results of the 2020 general election saw a 8.62% swing against the PAP
