The Electoral Boundaries Review Committee is made up of senior civil servants and charged with adjusting the boundaries of electoral divisions prior to an election. The government officially claims this as necessary to ensure minority participation in Parliament amidst demographic changes while ensuring an equitable amount of voters represented per MP, though critics have raised allegations of gerrymandering to disadvantage the opposition.[45][46][47][48] As of 2015, there were 16 GRCs and 13 SMCs. Prime Minister Lee convened the committee on 1 August 2019 with instructions to reduce the size of GRCs and increase the amount of SMCs.[49][50] The exact date of formation was revealed only when Opposition Leader Pritam Singh asked Trade and Industry Minister Chan Chun Sing in a written reply in Parliament.[51]
