HM Judiciary, represented here by the master of the rolls and lord chief justice, hit a distinctive sartorial note on Monday’s London Legal Walk. T-shirts and trainers were worn, but frequently over double-cuffed shirts and ties, and creased trousers. Exotic headgear was optional.

Despite the mature years of some participants, the 10k event passed off without mishap. When one runner took a tumble at Millbank, colleagues were ready with sympathy rather than PI business cards.

Some, however, found it hard to switch off. Attorney general Dominic Grieve used the early part of the walk to plan a speech with his assistant. And as for the lawyer who spent 20 minutes on the phone to a client, Obiter is not sure whether to applaud or cry.
