MADRID, May 3 (Reuters) - Herve Falciani, a former HSBC employee who leaked information on the bank's clientsand tax situation, told Spanish newspaper El Mundo he hadknowledge of other cases and could act again, adding his "workwas not done".
Falciani previously said that media leaks on HSBC accountsheld in Switzerland, which unleashed a public storm around theBritish bank, were "only the tip of the iceberg", and that taxauthorities had access to a lot more data.
The former information technology worker at HSBC's Swisssubsidiary hinted in the interview published on Sunday that hecould be moved to make more revelations.
"My work is still not done. We're not in a hurry. It'spossible that at the end of the year, we'll have the opportunityto act," he said, asked by El Mundo whether he would lift thelid on further tax cases if Spanish authorities did not.
Several high-profile Spaniards have been affected by theFalciani leaks.
The International Consortium of Investigative Journalists,which in February coordinated the media release of details ofleaked client data, said account-holders included ex-Santander Chairman Emilio Botin, who died last year.
Spanish authorities are also coming under pressure fromopposition parties to reveal which public figures feature on alist of people who signed up to a recent tax amnesty, especiallyas a general election nears. They have so far said theinformation is confidential.
"It's only a question of political will to uncover thatthere is 10 times more than what we discovered at HSBC,"Falciani is quoted as saying in the interview.
Falciani told El Mundo he had never worked alone in tryingto uncover tax data at HSBC.
"From the beginning, I did everything with the help ofothers," he said. He added that there were several people withinthe bank who shared his views and that he had asked for helpfrom contacts he had among police and customs specialists inMontecarlo.
Falciani did not specify what kind of help they hadprovided. (Reporting by Sarah White; editing by Jane Baird)
