Bird & Bird is celebrating one of the best half year performances in its history, growing by 24 per cent over the last six months.

The firm has added nearly a quarter to its half year revenue, ending on £68.5m.

Managing partner David Kerr said: “I think we’ve expanded a lot internationally. We’re finding that cross-border transactions and stronger client relationships are fuelling growth.”

Kerr said that the credit crunch had little effect on Bird & Bird’s growth this year, thanks to the firm’s practice area spread: “We have a healthy mix of work in areas such as IP and corporate, which really helps through this kind of period.”

Bird & Bird has pursued an expansive strategy in Western Europe, bringing in numerous lateral hires to boost its offices.

The firm’s base in The Hague has welcomed five partners this year alone, making it one of the fastest growing offices in Bird & Bird’s European network. Last week the office took a four lawyer customs and trade team from the Rotterdam office of Simmons & Simmons.
