Austria and Luxembourg are preparing to ease longstanding and controversial bank secrecy rules, allowing other EU member states access to their depositors' account details amid mounting pressure to crack down on tax evasion in Europe.
Tax havens have come under increasing scrutiny after millions of bank records were leaked last week exposing the identities of thousands of tax cheats around the world.
It also follows the explosive admission by Jérôme Cahuzac, until last month France's budget minister, that he had lied about holding a secret bank account in Switzerland, a revelation that has damaged François Hollande's presidency.

Werner Faymann, Austria's chancellor, said on Tuesday the country was ready to talk about providing details on EU citizens with offshore accounts in the country, although he insisted details about Austrian depositors would remain private.
"We are prepared to negotiate about automatic data-exchange concerning the accounts of foreigners in Austria that has been requested by the EU," he said.
Until now, he said, Austria had provided data only when there was evidence of wrongdoing. "That is too little. We need to act faster and more aggressively in the fight against tax fraud."

Meanwhile, Luc Frieden, Luxembourg's finance minister, said the EU's second smallest state would discuss easing banking secrecy rules and enhancing co-operation with other EU tax authorities to fight evasion. Speaking on the sidelines of a conference in London, Mr. Frieden told reporters that plans to share details of Luxembourg-based depositors were "under consideration" by the government.
