Ashurst has posted a 17% increase in turnover to smash through the £300m barrier, joining top 10 City rival Simmons & Simmons in announcing a double-digit increase in revenue.

The firm raked in fees totalling £323m for 2007-08, during which time the firm has made a series of hires in Europe and Asia, overhauled its lockstep and converted to a limited liability partnership.
