Social Democrats supported a compulsory dual mandate, to ensure that the state's MEPs expressed the same views as the national legislature, and the government of Denmark supported a compulsory dual mandate when the other eight member states supported an optional dual mandate. However, a 1976 European Parliament law preparing for the 1979 elections expressly permitted a dual mandate. In 1978 the German politician Willy Brandt suggested that one third of MEPs should be national MPs. Australia Dual mandates are rare in Australia. It is illegal to be a member of any state parliament and the Australian Parliament simultaneously. A member of a state parliament seeking federal office must resign before seeking election to the Federal Parliament. It is possible but unusual to be a member of a local government and another parliament. A recent example is Dr Kerryn Phelps who maintained her position as a Councillor on the City of Sydney Council while sitting in Federal Parliament as the Member for Wentworth between 2018 and 2019. In 2004 Clover Moore became the independent member for Sydney in the NSW Parliament without resigning as Lord Mayor of Sydney. The issue of Moore holding both positions had brought the issue to the forefront in Australia and led the premier of New South Wales in 2012 to propose a new law, dubbed in the media as the "Get Clover bill", which banned this dual mandate. The proposed law was adopted and in September 2012 Moore resigned her NSW seat soon after she was reelected as mayor. Belgium As in neighboring France, the culture of dual mandates is very strong in Belgium and that country currently has one of the highest percentage of dual mandate holders (MPs, aldermen, municipal councilors) in the world. During the 2003–2009 period, 87.3% of members of the Walloon (French-speaking) Parliament held dual mandates, followed by 86.5% in the Flemish (Dutch-speaking) Parliament, 82.0% in the Chamber of Representatives (the Federal lower house) and 68.9% in the Senate. During that same period, 76.5% of all European Parliament MPs from Belgium held dual mandates. More than one-fifth of all Belgian MPs were mayor at the same time with, by far, by the highest proportion (40%) to be found in the Walloon Parliament. Canada In Canada dual mandates are rare and are frequently barred by legislation at the federal, provincial, or territorial level. At the federal level, section 39 of the Constitution Act,
