German minister Annette Schavan quits over 'plagiarism' 9 February 2013 Last updated at 14:22 German Education Minister Annette Schavan has resigned after a university stripped her of her doctorate for plagiarism. Duesseldorf's Heinrich Heine University voted last Tuesday to remove her doctorate following a review. Ms Schavan, a close ally of Chancellor Angela Merkel, insisted she would still fight the university's ruling. In 2011, Defence Minister Karl-Theodor zu Guttenberg also quit after allegations he plagiarised his thesis. Johanna Wanka, the culture and science minister of the state of Lower Saxony, has been appointed as Ms Schavan's successor. Germany's biggest selling newspaper, Bild, said that the education minister being caught plagiarising was as though the finance minister was revealed to have a secret Swiss bank account or the transport minister being caught drinking and driving. Germany has some form when it comes to politicians and plagiarism. The latest scandal follows that of Karl-Theodor zu Guttenberg, who was similarly caught with sections of his dissertation being the work of others. It led to him being dubbed in the press Dr Cut-and-Paste and Dr zu Googleberg. These cases occur in Germany partly because of the German obsession with titles. German politicians take them very seriously, seeing them as a mark of intellectual respectability. It is not uncommon, for example, for a professor with two doctorates to expect to be called 'Professor, Doctor, Doctor'. Part of the education minister's brief is to oversee German universities. Nation first Addressing Mrs Merkel with the words "Dear Angela,," Ms Schavan thanked the chancellor for her friendship. "I think today is the right day to leave my ministerial post and to concentrate on my duties as a member of parliament," the 57-year-old said. I will not accept the university's decision and will take legal action. I have never copied nor plagiarised. The accusations hit me very hard. Ms Schavan added that her main priority was to protect her department and the government. "First the nation, then the party, then myself," Ms Schavan said, citing words used by former state prime minister Erwin Teufel. When an education minister sues a university, then that comes with strains, for my office, for the ministry, and for the Christian Democrats. I want to avoid just that. The university of Dusseldorf decided to look into Ms Schavan's 1980 doctoral thesis after an anonymous blogger raised questions about it. The faculty committee found she had "systematically and intentionally" copied parts of her thesis, Person and Conscience. Ms Schavan had been scathing in her criticism of Mr Guttenberg when the scandal of his plagiarism broke. "As someone who was herself awarded a doctorate 31 years ago and who has supervised several doctoral candidates, I am ashamed and not just behind closed doors," she told the Sueddeutsche Zeitung at the time. Analysts say her resignation will be hugely embarrassing to Mrs Merkel. The chancellor is facing federal elections on 22 September. She said she accepted the resignation "with a heavy heart."
