Political unrest in the Ukraine is likely to pose corruption risks for U.K. banks, warns Transparency International, a global anti-corruption coalition. It is urging comprehensive sanctions and anti-money laundering efforts in the U.K. and financial centers around the world.

โ€œYour government has invested in learning from the experience of slow international response to freezing corrupt assets in wake of the Arab Spring,โ€ the group wrote in a Feb. 21 letter to U.K. Chancellor of the Exchequer George Osborne. โ€œThose lessons should now be applied to the situation in the Ukraine. [The government] should, without delay, take a proactive role to remind all risk sectors, and their relevant regulators, of their obligations to examine money laundering risks related to members and associates of the current Ukrainian regime.โ€
