In a statement, Selmeczi said Gyurcsany was by now a laughing-stock.
“When will he notice that he is by now pathetic and everyone is laughing at him, including his one-time left-wing comrades?” she wrote.
Gyurcsany is accused of having copied the dissertation of his brother-in-law in 1984.
The Fidesz politician said Gyurcsany should make clear what he meant by “used and spooned out” when it came to the work of his brother-in-law written in 1980, and why the two graduation papers shared the same title and, according to records, exactly the same number of pages.
The Democratic Coalition said in a statement to MTI on Saturday that Gyurcsany would sue HirTV, the television news channel which investigated the case.
