David Green QC, director of the Serious Fraud Office, has said there will be “significant developments” in the agency’s Libor investigation, as the SFO prepares for the next stages in its prosecution next month.

In a speech to the Cambridge International Symposium on Economic Crime yesterday, Green reasserted the SFO's tough stance over the manipulation of the interest rate benchmark, as the agency gears up for the next hearings of the three individuals facing Libor charges in October.
