Allies of Hungary’s far-right prime minister Viktor Orbán will hold a closed-door meeting with Republicans in Washington to push for an end to US military support for Ukraine, the Guardian has learned.

Members of the Hungarian Institute of International Affairs and staff from the Hungarian embassy in Washington will on Monday begin a two-day event hosted by the conservative Heritage Foundation thinktank.

The first day includes panel speeches about the Ukraine war as well as topics such as Transatlantic Culture Wars. It is expected to feature guests including Magor Ernyei, the international director of the Centre for Fundamental Rights, the institute that organized CPAC (Conservative Political Action Conference) Hungary. Kelley Currie, a former ambassador under then president Donald Trump, said she was invited “but declined”.
