So what does Jenkins, who once represented Scotland as a sprinter, do to earn his fabulous salary? It is a question that Barclays Capital would prefer was not asked because, in its simplest form, Jenkins and colleagues Ian Abrahams and Mike Keeley spend their days working out clever ways to slash the tax bills of companies, including Barclays.

Every bank in the City employs a structured finance division that performs the same role, but none is believed to be anywhere near as successful as either Barclays Capital or Jenkins.
