EU leaders voiced concerns Thursday at rumours that Hungarian premier Viktor Orban — at the helm of the EU presidency — was about to travel to Moscow, with Council President Charles Michel saying there was "no mandate" for it.

Orban is the only EU leader to have maintained close ties with the Kremlin following Russia's invasion of Ukraine in 2022.

On Monday, Hungary took over the European Union's rotating presidency, giving the central European country sway over the bloc's agenda and priorities for the next six months.
