Mr. Corbyn’s tough remarks followed a report released earlier this week by the leading global financial services firm which said that the risks of an incoming Labour government could be "as significant as Brexit".
“Their greed plunged the world into crisis and we're still paying the price, because the Tories used the aftermath of the financial crisis to push through unnecessary and deeply damaging austerity," Corbyn said in a video message, describing bankers as "speculators and gamblers."
Labour is a "government-in waiting, so when they say we're a threat, they're right. We're a threat to a damaging and failed system that's rigged for the few,” he added.
In October, Britain’s ex-premier Gordon Brown said a 2008-style bank crash could happen again, forcing UK taxpayers to fund another multi-billion pound rescue package.
He insisted rogue banking executives should have been jailed, stripped of their bonuses and had their assets confiscated after Britain experienced the worst financial crisis since the Depression of the 1930s.
The financial crisis of 2007–2008, also known as the global financial crisis, began in 2007 with a crisis in the subprime mortgage market in the US, and developed into a full-blown international banking crisis with the collapse of the investment bank Lehman Brothers in September 15, 2008.
The crisis played a significant role in the failure of key businesses, declines in consumer wealth estimated in trillions of US dollars, and a downturn in economic activity leading to the Great Recession of 2008–2012 and contributing to the European sovereign-debt crisis.
