US Vice-President JD Vance is visiting Hungary to support Prime Minister Viktor Orban in a challenging parliamentary election. Orban faces competition from Peter Magyar, a former ally. The election is significant as it could impact Hungary's relationship with the US and its energy policies amid tensions with Ukraine and Russia. Orban's campaign includes a focus on anti-Ukrainian sentiment and recent scandals have affected his popularity. Vance's presence is seen as a potential boost for Orban's re-election chances.
