Buckingham Palace denies that King Charles met with European Commission President Ursula von der Leyen.

The Palace spokesperson said the King is happy to see visiting foreign leaders on government advice.

In a statement, Downing Street said that meeting Ursula von der Leyen was mostly up to the Palace and the King.

The meeting will discuss climate change, Ukraine, and the new Brexit agreement for Northern Ireland.

The King and Ms. Von der Leyen's meeting was cancelled days before an expected settlement was announced.

The meeting was dubbed the "Windsor Agreement" by government officials.

The DUP's Brexit spokesman, Sammy Wilson, said that involving the King would be "a cynical use or abuse" of the monarch.

Former Tory Business Secretary and Euroskeptic Jacob Rees-Mogg told The Times that the meeting with the Queen was "on the border of constitutional validity."

Charles could be seen as "endorsing, if not blessing," the possible new deal if he meets with Ms. Von der Leyen today.
