White & Case’s London office has significantly increased its annual contribution to the global firm’s central running costs, with a 70% hike to £17.7m for the 2011 financial year.

The increase comes after the amount the City office paid in to central running costs rose 40% last year to £10.4m. The UK base’s contribution to global costs has grown steadily since 2008, when it stood at £4.7m, before rising to £7.4m in 2009.
