Latest LLP accounts filed with Companies House reveal that the firm had 61 members in 2008-09 -10 more than in 2007-08 – and that the number of non-partners at the firm also increased over the same period.
The growth in headcount helped boost overall turnover, which grew by 22 per cent to hit £59.4m.
International income increased by 50 per cent during the last financial year, and now makes up over a third of total revenue.
The firm brought in £21.9m from its non-UK European and South East Asian offices during 2008-09, compared with £14.6m for these overseas offices during the previous financial year.
The largest amount was from its European offices, which together brought in £13.1m, while the South East Asian offices in Bangkok and Singapore made £8.7m.
The increasing importance of the international offices was reflected in the promotions to the partnership in May 2008. Out of a total of nine new partners, four were made up abroad, with one promotion each in Bangkok, Paris, Rome and Singapore.
