Banks are facilitating international corruption by doing business with the world's dictators, according to a report today by an anti-corruption campaign group. Global Witness calls for banks to work harder to turn away business from individuals who pose a corruption risk… Banks named in the report include Barclays… Barclays declined to comment because of client confidentiality. Other banks "hid behind bank secrecy laws" to frustrate US inquiries, the report says… Gavin Hayman, campaigns director of Global Witness, said…"Government must take responsibility to stop banks doing business with corrupt dictators and their families."
