Lukashenka postponed his inauguration yesterday without explanation. Milinkevich's statement could not be independently confirmed.
In Poland, Milinkevich thanked Polish universities for offering to accept Belarusian students expelled from universities for taking part in anti-Lukashenka rallies.
"The signing of an agreement among rectors of Polish universities is a very important development, because those students who are being and have been expelled from Belarusian universities will have an opportunity to continue their studies," the opposition leader said. " I think the Republic of Poland is providing enormous help by doing this."
Milinkevich is to lead a meeting of opposition forces on March 31 after returning to Minsk.
