Hungarian Prime Minister Viktor Orbán has congratulated US Republican presidential candidate Donald Trump on winning the elections despite the fact that official results are yet to be announced.

Hungarian Prime Minister Viktor Orban will host dozens of European leaders in Budapest later this week boosted by his "dear friend" Donald Trump's US election victory, but with relations with other EU states increasingly strained.

Hungarian Prime Minister Viktor Orbán is calling for a new EU strategy on Ukraine following Donald Trump's victory in the US presidential election. Since Trump might halt US aid to Kiev in its defence against Russia,

Europe will need to rethink its support of Ukraine if Donald Trump is elected president of the United States, Hungarian Prime Minister Viktor Orban said on Sunday, as the continent "will not be able to bear the burdens of the war alone".

The party of Hungarian Prime Minister Viktor Orban slipped behind that of his upstart challenger Peter Magyar in a second opinion poll in as many days, pointing to a potentially close parliamentary election in 2026.

Orban, who has grown increasingly isolated within the EU for his ties with Russia and opposition to military aid for Ukraine, has praised Trump as a "man of peace" who would quickly end the war. The two spoke by phone late on Wednesday, and Orban posted on social media: "We have big plans for the future".

So what will the future Trump presidency mean for the continent? And in particular, for Ukraine? Ukraine's Volodymyr Zelensky is in the Hungarian capital for a meeting of the European Political Community.
