London, England

Pimco's Bill Gross, billionaire investor George Soros and the International Monetary Fund have all criticized the U.K. government's austerity plan.Yet, finance minister George Osborne is sticking to the controversial policy.

Last week, Fitch became the second ratings agency to cut the U.K.'s triple-A rating. Osborne has insisted the U.K. must stay the course as public sector net debt has ballooned to 1.2 trillion pounds ($1.85 trillion) or 75.4 percent of GDP.
