At BarCap, as it became known, Diamond ran a battle-hardened team of loyalists under the famous “no jerks” rule. This said that anyone who rocked the boat, fell out with colleagues or embarrassed the bank in any way was cut loose without hesitation. When it emerged that a rowdy group of BarCap investment bankers had lavished £44,000 on a meal at the St James’s restaurant Petrus to celebrate a deal, they were sacrificed. In a newspaper interview Diamond said “to have acted in that way was inexcusable”.
