EY is stepping up its US governance overhaul efforts, a bid to give partners there a greater voice in firm strategy, following the failed separation of its audit and advisory businesses earlier this year.

The proposal comes as the Big Four accounting firm continues to work to untangle the mess left by its decision in April to scrap plans to split auditing and consulting into two different firms. EY spent $600m (£480m) and more than a year working on the split.
