Weil Gotshal & Manges' City arm has posted a 3.6% increase in revenue for 2013, as its global profit and turnover both suffered significant falls.

The London office generated $114m (£68.6m) in fee income last year, up on the previous year when it brought in $110m (£66.2m).

The improved performance came despite partner headcount at the City office dropping from 31 to 28, with legal staff numbers also down from 119 to 114.

There has been a slew of partner exits at Weil in London since the start of 2013. City capital markets head James Cole joined Paul Hastings in January 2013, while private equity partner Mark Soundy left to join Shearman & Sterling with City tax head Sarah Priestley and associate Simon Burrows in May. This was followed by litigator Matthew Shankland's departure to Sidley Austin and tax partner Brenda Coleman's exit to Ropes & Gray.

Funds partner Nick Benson joined Latham & Watkins in January and finance partner Rob Ferguson left the firm last September.

Firmwide, revenue dipped by 7.3% from $1.23bn (£736m) to $1.14bn (£682m) while profit per equity partner (PEP) saw a similar drop of 7.1% to stand at $2.07m (£1.24m). The firm's 2012 PEP was $2.23m (£1.33m).

Last June the firm announced a redundancy round affecting 170 lawyers and support staff, reducing associate headcount by around 60, with roughly 110 support staff positions also set to go.

Since then, more than 30 partners have left, including at least 17 partners based in Houston and Dallas, as well as several senior partners from the firm's east coast bases.
