Herbert Smith, Pinsent Masons and Barlow Lyde & Gilbert have all secured roles on a £22m case against a barrister, which is set to go to court later this month.

The negligence claim, which is thought to be one of the largest cases ever pursued against a barrister, was brought against tax specialist Adrian Shipwright of Pump Court Tax Chambers and accountancy firm Baker Tilly by approximately 75 claimants.
