BP has appointed Three Crowns, the boutique firm launched earlier this year by six prominent arbitrators, as the sole provider of arbitration services on its niche legal panel of UK advisors.

The arbitration group is joined by eight other firms selected by the oil major to provide certain specialist legal services: Baker & McKenzie, Hill Dickinson, Holman Fenwick Willan, Reed Smith, Stevens & Bolton, Sullivan & Cromwell and Watson Farley & Williams.
