Denton Hall managing partner Jonathan Tatten is to step down, sparking a management shake-up at the 120-partner firm.

His decision not to stand for re-election ends a rollercoaster six years for Tatten which saw him unsuccessfully attempt to forge two tripartite mergers.

The move has prompted Dentons' board to propose a new structure, which would see management of the firm divided between one managing partner for the UK and one for the rest of the world.
