In 2006, major nationwide protests erupted after it was revealed that Prime Minister Ferenc Gyurcsány had claimed in a closed-door speech that his party "lied" to win the recent elections. The popularity of left-wing parties plummeted in the ensuing political upheaval, and in 2010, Viktor Orbán's national-conservative Fidesz was elected to a parliamentary supermajority. The legislature consequently approved a new constitution, among other sweeping governmental and legal changes. Although these developments were met with and still engender controversy, Fidesz secured a second parliamentary supermajority in 2014 and a third in 2018. In the late 2010s, Orbán's government came under increased international scrutiny over alleged rule-of-law violations. In 2018, the European Parliament voted to act against Hungary under the terms of Article 7 of the Treaty on European Union. Hungary has and continues to dispute these allegations.
