Péter Magyar is preparing to be sworn in as Hungary's new prime minister following his Tisza party's decisive electoral victory that ended Viktor Orbán's lengthy hold on power.

The electoral results, confirmed nearly a month ago, saw Magyar's opposition party secure what has been characterized as a landslide win against Orbán's Fidesz party, which had governed Hungary since 2010.

Orbán's departure marks the end of a significant era in Hungarian politics. During his 16-year tenure, the longtime leader implemented policies that often put Hungary at odds with European Union institutions and drew criticism from Western allies over concerns about democratic backsliding and press freedom.

Magyar's victory represents a major shift in Hungary's political landscape. The Tisza party campaigned on a platform that promised to restore democratic norms and improve relations with European partners.

The swearing-in ceremony is expected to take place amid celebrations by Magyar's supporters, who view the electoral outcome as a fundamental change in Hungary's political direction. The transition comes at a time when Hungary faces various economic and diplomatic challenges within the European Union framework.

Details about Magyar's immediate policy priorities and cabinet appointments are expected to be announced following the official ceremony.
