Germany's president resigned Friday in a scandal over favors he allegedly received before becoming head of state, and Chancellor Angela Merkel moved quickly to try and head off a domestic political crisis as she grapples with Europe's debt troubles.
Christian Wulff, who was Merkel's candidate for the presidency when elected less than two years ago, quit after two months of allegations he received favors such as a favorable loan and hotel stays from friends when he was governor of Lower Saxony state.
Pressure mounted after prosecutors in the state capital, Hannover, asked Parliament Thursday to lift his immunity so they could start a formal investigation of allegations related to a film producer friend.
Merkel, who called off a trip to Rome on Friday, voiced deep regret at his resignation. She moved quickly to limit the fallout and try to ensure a smooth succession, saying she would seek an agreement with the main opposition parties on the next president.
Wulff, 52, was a deputy leader of Merkel's conservative Christian Democratic Union before becoming president in a messy 2010 election in which the opposition's candidate, well-regarded former East German human rights activist Joachim Gauck, drew votes from Merkel's center-right coalition.
Prosecutors said there was an initial suspicion that Wulff improperly accepted or granted benefits in his relationship with David Groenewold, a German film producer whom they also plan to investigate. Those benefits allegedly included Groenewold paying for a luxury hotel stay in 2007.
Wulff said he was stepping down because Germany needs a president who is supported by the confidence not just of a majority of citizens, but a wide majority.
The developments of recent days and months have shown that this confidence, and therefore my ability to act, has been lastingly impaired, a somber Wulff said in a brief statement at the president's Bellevue palace, with his wife, Bettina, at his side.
The speaker of Parliament's upper house, conservative Bavarian governor Horst Seehofer, will take over the presidential duties on an interim basis, mostly signing legislation into law.
A special parliamentary assembly made up of lower-house lawmakers and representatives of Germany's 16 states must elect a successor within 30 days.
Wulff follows his predecessor, also nominated by Merkel, in resigning early. In mid-2010, Horst Koehler quit abruptly a year into his second five-year term, citing criticism over comments he made about the German military.
