A leadership challenge at Washington law firm Crowell & Moring has seen its defeated chair exit the firm. Angela Styles, who was chair of the firm since 2015, was beaten by white collar crime partner Philip Inglima in an election in September. She was expected to hand over the reins early next year. However, she has left the firm already, saying several opportunities had arisen which she was considering. Her stint at the top saw revenues rise by 20 per cent to $434.5 million whilst profits per equity partner were up 30 per cent ot $1..45 million last year. Ms Styles was the second female to lead the firm - Rosemary Collyer had earlier held the post.
