The leaders of the 27 European Union countries sealed a deal Thursday to provide Ukraine with a new 50-billion-euro ($54 billion) support package despite Hungary’s weeks of threats to veto the move.

European Council President Charles Michel announced the agreement about only an hour into the leaders’ summit in Brussels.

“We have a deal,” Michel said in a post on X, formerly known as Twitter. He said the agreement “locks in steadfast, long-term, predictable funding for Ukraine,” and demonstrated that the “EU is taking leadership and responsibility in support for Ukraine; we know what is at stake.”

It was not immediately clear if any concessions were made to secure Hungarian Prime Minister Viktor Orban’s approval. He raised staunch objections to the financial aid package in December and in the days leading up to Thursday’s summit in Brussels.
