"Dear Mr. President." What was in the invitation from the Prime Minister?

President Andrzej Duda, by not coming to this ceremony, actually deprived himself of the attention he deserved in this situation. I think that he did it to spite himself - said Agata Adamek, a reporter from TVN24, in the program "W kuliarach". The president did not appear at the gala inaugurating the Polish presidency of the EU Council, despite an authoritative invitation from the prime minister sent earlier.
