"Today, as tyranny once again threatens Europe, we and our allies stand together in support of Ukraine, to deter aggression and secure peace," says King Charles in his state banquet speech, APA reports citing BBC.
It's an important message that the UK government and other Nato allies will want to send to President Trump.
The King links this modern threat to democracy with the wartime alliance of the US and UK.
"Our countries have the closest defence, security and intelligence relationship ever known," says the King.
