* Informant offers data of 1,500 possible tax evaders- paper
* Most accounts are from Swiss banking flagship UBS - paper
* Case may prompt fresh row between Switzerland and Germany
BERLIN/ZURICH, Jan 31 (Reuters) - German politicians were divided at the weekend over whether to buy the secret bank data of 1,500 possible tax evaders with accounts in Switzerland that media say an informant has offered to sell authorities.
The respected Frankfurter Allgemeine Zeitung reported that the whistleblower is asking for 2.5 million euros for the confidential data, which tax investigators believe could rake in 100 million euros for German state coffers.
The case, which German daily Handelsblatt says involves accounts mostly from Swiss banking flagship UBS, risks prompting a fresh row over bank secrecy between Germany and Switzerland. Top Swiss politicians, including President Doris Leuthard, and bankers warned Germany against acquiring the data.
UBS (UBS.N) UBSN.VX, which has been bailed out by the Swiss government and accused of helping rich Americans dodge taxes, said it was not aware of any such information. “At this point in time this is speculation,” it said in a statement.
A spokesman for the German Finance Ministry declined to comment on the report but said it would be the responsibility of individual German states to deal with such data.
A senior ally of Chancellor Angela Merkel, Defence Minister Karl-Theodor zu Guttenberg, said Germany would have to carefully check its legal right to purchase the alleged data.
“I have a problem with handing over money for something that has come into someone’s possession in a legally questionable fashion,” Guttenberg told Swiss daily Neue Zuercher Zeitung.
Members of the opposition Greens and Social Democrats (SPD) however encouraged the government to buy the data on behalf of “honest taxpayers”.
Nicolette Kressl, SPD finance expert, told Die Welt am Sonntag the government should proceed as it did in 2008, when it purchased data on tax evaders from an informant about clients of a Liechtenstein bank.
The case snared former Deutsche Post chief Klaus Zumwinkel, who was given a suspended jail term for evading nearly a million euros in taxes using a Liechtenstein trust. [ID:nLM752092]
Former Finance Minister Peer Steinbrueck repeatedly accused Germany’s neighbours Switzerland, Liechtenstein and Luxembourg of serving as havens for German tax evaders, but the three countries have taken steps in the last year to improve transparency on taxes amid a global crackdown on tax havens.
