A reveler dressed as Batman gestures beside a caricature of Germany's Defence Minister Karl-Theodor zu Guttenberg (R) as they attend a carnival parade in Berlin, February 27, 2011. Carnival processions in Germany are held immediately before the period of Lent, with revelers dressing up in fantasy costumes, dancing in the streets and mocking politicians and other people in the public sphere. The popularity of the Defence Minister, an ally of Chancellor Angela Merkel, fell after he admitted to flaws in his doctorate that is the focus of a plagiarism row, a poll found on Friday.
