In May 2010, Lee instituted electoral reforms to the current electoral system by reducing the number of group representation constituencies (GRC), increased the number of Non-constituency Members of Parliament (NCMPs) to a maximum of nine (inclusive of the number of elected opposition members of Parliament), and the number of Nominated Members of Parliament (NMPs) permanent also to nine. Also part of the reforms was the legalization of internet campaigning and mandating a "cooling-off" day where campaigning is prohibited except for party political broadcasts.
