London lawyers have made up around 10% of US firms' overall partnership additions in the latest promotions round.

The latest firms to announce their promotions are Dechert, Jones Day and McDermott Will & Emery, which between them have named 98 lawyers as partners worldwide, although only nine of those are London based.

Dechert's promotions came primarily across the firm's Philadelphia and New York offices. Real estate finance lawyer Kimberley Andrascik was the only UK addition. She will split her time between London and Philadelphia.

Cleveland giant Jones Day made up 46 new partners worldwide, including two in Singapore and one apiece in Hong Kong and Taipei. Four lawyers got the nod in London – Rosalind Connor (employment), Tim Flood (regulation), Vica Irani (capital markets), and Andrew Barker (finance).

Of the 43 promotions at McDermott, eight were split over its five European offices. Brigid Breslin (corporate), Rohan Massey (IP), Prajakt Samant (corporate) and Stuart Sinclair (tax) were all made up in London.

The figures follow announcements by New York leaders Simpson Thacher & Bartlett and Sullivan & Cromwell, which added just one partner each in London. O'Melveny & Myers also added just one City partner out of 23 promotions in all. Weil Gotshal & Manges appointed two partners from 20 and Shearman & Sterling and Latham & Watkins made up two City-based partners out of 42 worldwide.

Bingham McCutchen, Cleary Gottlieb Steen & Hamilton, Morrison & Foerster (MoFo) and Willkie Farr & Gallagher all chose not to appoint any new partners in their London offices.

MoFo London head Julian Thurston said: "The practice groups in London decided not to put anybody forward this year, having made two up last year, as well as some lateral hires. I am sure that if we had, the firm would have supported us. In our case it is not indicative of any trend."

Lawyers in the London office of Dewey & LeBoeuf fared better than most of their peers, with four out of 18 partnerships coming in London just before Christmas. Also bucking the trend were Mayer Brown and White & Case, which gave partnerships to 20 London lawyers between them.
