Caroline Ellison has been sentenced to two years in jail for her role in the collapse of the cryptocurrency exchange FTX, which has been described as one of biggest financial frauds in US history.

Ellison was a top executive at the firm and is also the ex-girlfriend of its founder, Sam Bankman-Fried, who was sentenced to 25 years in prison for stealing $8bn (£6.3bn) from customers.

As part of a plea deal, Ellison admitted charges including wire fraud and money laundering, and testified against Bankman-Fried.
