In most cases, these populist leaders built a political organisation around themselves, typically a political party, although in many instances these remain dominated by the leader. These individuals often give a populist movement its political identity, as is seen with movements like Fortuynism in the Netherlands, Peronism in Argentina, Berlusconism in Italy and Chavismo in Venezuela. Populist mobilisation is not however always linked to a charismatic leadership. Mudde and Rovira Kaltwasser suggested that populist personalist leadership was more common in countries with a presidential system rather than a parliamentary one because these allow for the election of a single individual to the role of head of government without the need for an accompanying party. Examples where a populist leader has been elected to the presidency without an accompanying political party have included Peron in Argentina, Fujimori in Peru, and Correa in Ecuador.
