The Serious Fraud Office (SFO) has invited Barclays to discuss a potential deal that will close the SFO’s criminal probe into the bank’s £2 billion Qatari fundraising in 2008. Recent news reports suggest that Barclays is considering if it should accept a deferred prosecution agreement (DPA) with the SFO but sources familiar with the situation says that under a DPA, the company will be slapped with a hefty fine and held under tighter terms and conditions.
