The German government has been offered a new set of details of bank accounts in Liechtenstein, in what could be the latest intelligence coup in Germany’s Europe-wide campaign to track down tax evaders.

The finance ministry in Berlin confirmed German media reports on Friday that lawyers representing an informant had on February 25 contacted a deputy finance minister to discuss the data, which allegedly includes information on 2,300 bank accounts containing more than €4bn ($6bn, £3bn).
