<P> In recent decades, critics have accused the ruling People's Action Party (PAP) of unfair electoral practices to maintain significant majorities in the Parliament of Singapore . Among the complaints are that the government uses gerrymandering . The Elections Department was established as part of the executive branch under the Prime Minister of Singapore, rather than as an independent body . Critics have accused it of giving the ruling party the power to decide polling districts and polling sites through electoral engineering, based on poll results in previous elections . </P> <P> Members of opposition parties claim that the Group Representation Constituency system is "synonymous to gerrymandering", pointing out examples of Cheng San GRC and Eunos GRC which were dissolved by the Elections Department with voters redistributed to other constituencies after opposition parties gained ground in elections . </P> <P> Sri Lanka's new Local Government elections process has been the talking point of gerrymandering since its inception . Even though that talk was more about the ward - level, it is also seen in some local council areas too . </P> <P> In the most recent election of 2010, there were numerous examples of gerrymandering throughout the entire country of Sudan . A report from the Rift Valley Institute uncovered violations of Sudan's electoral law, where constituencies were created that were well below and above the required limit . According to Sudan's National Elections Act of 2008, no constituency can have a population that is 15% greater or less than the average constituency size . The Rift Valley Report uncovered a number of constituencies that are in violation of this rule . Examples include constituencies in Jonglei, Warrap, South Darfur, and several other states . </P>
