Milbank Tweed Hadley & McCloy and Kaye Scholer have becomes the latest Manhattan firms to announce strong year-end figures for 2006.

Total fee income at Milbank rose from $496.1m (£257m) in 2005 to $540.8m (£280m) for the following 12-month period – an increase of 9%. Meanwhile, profits per equity partner (PEP) climbed 7% from a figure of $2.02m (£1,048,452) in 2005 to a new mark of $2.17m (£1.12m).
