Slaughter and May and Allen & Overy (A&O) have become the latest magic circle firms to announce their partner promotions, with 23 made up at A&O and two added to the senior rank at Slaughters.

The Slaughters promotions are shared between the firm's London and Hong Kong offices, with financing lawyer Ed Fife made up in London. Fife has been at the firm since joining as a trainee in 2003 and has handled work for key clients including Akzo Nobel, ISS, GlaxoSmithKline and First Group.

Meanwhile, dispute resolution lawyer Mark Hughes has been promoted in Hong Kong. Hughes also trained at the firm in London, joining two years before Fife in 2001. He has been based in Hong Kong since 2010.

The two additions take total partner headcount at Slaughters to 122, of which 22 are female. Broken down by geography, 111 of the firm's partners are based in London, with the remainder shared across its bases in Brussels, Beijing and Hong Kong.

This year's round comes after Slaughters made up five to its partnership last year, in the firm's largest promotions round in recent years. Two lawyers were made up in 2010 and 2009, with four in 2008.

Meanwhile, A&O has promoted 23 lawyers to the partnership across 14 of its offices. This year's round includes nine new female partners, a significant increase on the two female promotions the firm made last year.

The new partners are spread across the antitrust, banking, corporate, employment, capital markets and litigation practices, with the round also slightly larger than last year, when 21 lawyers were made up.

A&O managing partner Wim Dejonghe (pictured) said: "These global promotions reflect the cross-border nature of our work and the strength of our international network, the largest of any of the elite law firms.

"The retention of our female lawyers through to partnership remains one of our key priorities and it is great to see us continue to retain such talent through to partnership."
