Nature reports that there has been a substantial accusation of plagiarism in the dissertation of the Prime Minister Victor Ponta. Just recently, the Minister of Education had to resign about a month ago because his dissertation was a plagiarism. Do scroll down to the update — the press office of the Romanian government set a misspelled nastygram to Nature, that they have published in all it's glory, accusing Nature of playing politics.
According to Nature, the Ethics Council that is still working on preparing a report on the plagiarism in the dissertation of the Minister of Education was sacked a few days ago.
Here is a link to the plagiarism documentation: http://media.tvrinfo.ro/other/201206/oglinda-vp-2003-teza_94614100.pdf (in Romanian, but the copying is clear if these are indeed true copies of both thesis and sources).
Update 2012-07-03: Found an Austrian article on the topic "Von Guttenberg zu Ponta". Apparently Ponta had told El Pais that he would step down if his thesis was found to be plagiarized, and the committee did indeed determine that, but the committee was expanded from 21 to 45 people, so the legality of the determination is currently being disputed. Personally, I find all this legal maneuvering quite distasteful. This is a scientific problem - politics only needs to determine if it wants to keep a plagiarist on board, but the determination of plagiarism should be solidly in the hands of the university.
