KIEV, Feb. 11 – Ukraine's falling credit ratings indicates that its economy is one step away from irreversible downfall, Serhiy Tyhypko, deputy head of the ruling Regions Party's and former Deputy Prime Minister, said.

"The downgrading of Ukraine's rating to 'CCC' by Fitch is a yellow card for our economy. Aggressive anti-crisis measures are needed, and a new, effective, and qualified government is needed right now," the politician wrote in his blog on Facebook.
