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.
