Plaid Cymru in Wales and, to some extent, Sinn Féin in Northern Ireland (United Kingdom). In developing countries they include the Polisario Front in Western Sahara (Morocco), the National Movement for the Liberation of Azawad in Azawad (Mali), the Front for the Liberation of the Enclave of Cabinda in the Cabinda Province (Angola), and all national liberation movements. Federalist/autonomist regional parties include the Coalition Avenir Québec in Quebec (Canada), the New Progressive Party of Puerto Rico and the Popular Democratic Party in Puerto Rico (a commonwealth of the United States), Lega Nord in Northern Italy (the party has, at times, advocated Padania's independence and its "national section" in Veneto, Liga Veneta, is a proponent of Venetian independence), the Party of the Corsican Nation in Corsica (France), the Martinican Progressive Party in Martinique and the Communist Party of Réunion in Réunion (both French overseas territories), and the New Macau Association in Macau (China). In some countries, the development of regionalist politics may be a prelude to further demands for greater autonomy or even full separation, especially when ethnic, cultural and economic disparities are present. This was demonstrated, among other examples, in the Socialist Federal Republic of Yugoslavia in the early 1990s. Regional vs. regionalist political parties Political parties that are regional are not necessarily regionalist parties. A "regional party" is any political party with its base in a single region, whatever its objectives and platform may be, whereas "regionalist" parties are a subset of regional parties that specifically campaign for greater autonomy or independence in their region. Because regional parties – including regionalist parties – often cannot receive enough votes or legislative seats to be politically powerful, they may join political coalitions or seek to be part of a coalition government. Notable examples include the Sinn Féin's participation in the Northern Ireland Executive since 1999, the New Flemish Alliance's participation in the Federal Government of Belgium in 2014-2019, and Lega Nords frequent participation in the Italian government. Examples of regional parties that do not generally campaign for greater autonomy or federalism include most provincial parties in Canada, most regional and minority parties in Europe, notably including the Christian Social Union in Bavaria (Germany), most parties in Belgium, most parties in Northern Ireland, the Istrian Democratic Assembly in Istria and the Alliance of Primorje-Gorski Kotar in Primorje-Gorski Kotar (both counties of Croatia), and most political parties in India.
