On 21 May 2011, the Prime Minister announced the appointment of an independent committee to review the basis and level of political salaries to ensure that the salary framework remained relevant for the future. The review covered the salaries for the President, Prime Minister, Speaker of Parliament, Deputy Speaker of Parliament, political appointment holders, and Members of Parliament (MPs) including Non-Constituency MPs and Nominated MPs. The Committee's report was submitted to the Prime Minister on 30 December 2011 and converted into a White Paper, "Salaries for A Capable and Committed Government".[PDF, 932 KB] The Committee kept in mind three principles when determining political salaries: 1. Salaries must be competitive so that people of the right calibre are not deterred from stepping forward to lead the country. 2. The ethos of political service entails making sacrifices, and hence there should be a discount in the pay formula. 3. There should be a "clean wage" with no hidden perks. The revised salaries took effect from 21 May 2011. In 2017, the Prime Minister formed a new independent committee to review the salary framework to ensure that it remained appropriate and valid. The 2017 Committee affirmed the continued relevance of the salary framework.
