According to UK media, Walesa reckons the whole thing was "a provocation organised by the Polish embassy,".
According to that Polish article, in which Wałęsa is quoted, he says:
"Nie wiem, czy ktoś mi to zrobił specjalnie, czy ambasada nie potrafiła takiej prostej rzeczy załatwić. W każdym razie przy wyjeździe wszystko już było w porządku."
He says he doesn't know whether someone did this to him on purpose or not. Nothing about "a provocation".
Btw, what UK media?
I know that when Warsaw airport seriously increased the charges for using the VIP terminal there, several Warsaw embassies simply stopped using it for anything below head of state level.
What does it have to do with anything?
