Rishi Sunak and the European Commission President are set to meet in Windsor on Monday. Ursula Von der Leyen’s diary, published on the European Commission’s website, on Sunday appeared to confirm the meeting with Mr Sunak will take place in Berkshire.
The location online was later changed from “Windsor” to the “United Kingdom” instead.
Sources suggested on Friday that a new deal on the protocol could be called the “Windsor Agreement”.
There had been plans for King Charles to meet the president of the European Commission at Windsor Castle on Saturday but this was ditched for “operational reasons”.
But critics accused Mr Sunak of dragging the King into politics.
Government sources denied Sunak was intending to use King Charles to endorse his much-anticipated deal to end the row with the EU over the NI protocol.
Dominic Raab, who is Deputy Prime Minister and Justice Secretary, on Sunday reiterated that the monarch regularly meets heads of states.
Asked whether he could see how the meeting could have been interpreted as “dragging the monarchy into politics” on Sky News’ Sophy Ridge On Sunday programme, Mr Raab said: “The King, the monarch, regularly meets heads of states and heads of leading international organisations.
“The precise timing of it and the scheduling of it, actually, is for the Palace and for the monarchy to decide, it’s not something that we would impinge on.
“But part of the normal functions of the King would be to meet senior international figures.”
