Quinn Emanuel Urquhart & Sullivan

Quinn Emanuel Urquhart & Sullivan's London office has broken through the £100 million turnover barrier, alongside an 11% increase in profits.

The Los Angeles-headquartered litigation boutique grew its London revenues by 20% in its most recent financial year to hit £100.6 million, and boosted its profits by 11% to £67.2 million.

Richard East, senior partner of the firm's London office, said in a statement: "These results reflect hard work and the truly outstanding quality of our partners and associates. Quinn Emanuel is unquestionably the market leader in litigation-only practices in London."

Fellow co-managing partner Alex Gerbi added in a statement: "This has been another year of fantastic growth in London revenues with all areas of our practice contributing to our success. We remain very ambitious and believe that we can continue to grow our market share and further entrench our position as the 'go-to' disputes firm."

Headcount in the litigation boutique's London office grew over the course of the year, with the firm now consisting of 19 partners and 69 associates and of counsel.

Hires for the firm last year included Bird & Bird senior associate Alexandrine Ananou, who was brought on board as a partner to launch Quinn's London patent litigation practice, Covington & Burling partner Elaine Whiteford and Shearman & Sterling arbitration partner Mark McNeill.

Fellow U.S. headquartered firm King & Spalding has also announced positive results for its London base, with a 15% revenue increase in the city. Turnover at the firm grew to $55.7 million in 2019, up from $48.3 million in 2018.

King & Spalding announced its global financials in February. Revenues at the firm rose to $1.34 billion, as profits per equity partner hit $3 million for the first time.
