Paul Hastings Janofsky & Walker has posted robust year-end figures for 2006, with the firm's City office showing turnover rocketing by 84%.

Turnover at the Los Angeles giant was up by more than a fifth (22%) to reach $813.5m (£442m), while profits per equity partner (PEP) rose 21% from $1.33m (£728,000) in 2005 to $1.61m (£872,000) last year.

The firm's 40-lawyer London arm grossed $21.4m (£11m) for the 12-month period, against a figure of just $11.6m (£6m) the previous year.

Firm chairman Seth Zachery said the firm hopes to grow the London office by a further 30% over the next 12 months.

The firm's results come after Los Angeles rival Gibson Dunn & Crutcher last week announced its 2006 figures, with fee income up 8% to $809m (£411m) and profits climbing 7% to $1.75m (£888,000).

Meanwhile, Vinson & Elkins posted modest results for 2006 after a year in which the Texas leader has made significant strides in putting its Enron nightmare behind it.

Revenue at Vinson was up 4% to a new mark of $531.9m (£272.5m), while PEP climbed 5% from $1.07m (£548,000) in 2005 to $1.13m (£576,000).

Last month, the Houston-based firm was dismissed from a $40bn (£20.3bn) Enron-related securities class action – a suit which represented the last claim facing Vinson over the collapse of the disgraced energy giant.
