Profiles of leading secret account holders

One of Mongolia's most senior politicians says he is considering resigning from office after being confronted with evidence of his offshore entity and secret Swiss bank account.

"I shouldn't have opened that account. I should have included the company in my declarations," Bayartsogt Sangajav told the International Consortium of Investigative Journalists (ICIJ). "I don't worry about my reputation. I worry about my family. I probably should consider resigning from my position."

Bayartsogt, who says his account at one point contained more than $1 million, became his country's finance minister in September 2008, a position he held until a cabinet reshuffle in August 2012. He is now the deputy speaker of Parliament.

During those years he attended international meetings and served as governor of the Asian Development Bank and the European Bank of Reconstruction, pushing the case for his poor nation to receive foreign development assistance and investment.
