Tite & Lewis has lost highly-rated litigation partner Fiona Walkinshaw to Reynolds Porter Chamberlain.
Walkinshaw's departure is the latest in an exodus that has left the accountancy-tied firm with just 11 partners.
The Ernst & Young-associated firm axed three partners and 12 fee-earners last year, but it has also lost partners that it would rather have kept.
Walkinshaw, a former Andersen Legal lawyer, joined Tite & Lewis just last year.
Stephen Mayer, head of Reynolds' dispute resolution practice, told The Lawyer: "[Walkinshaw's] combination of litigation skills and high-quality financial services expertise will give our successful disputes practice significant extra strength."
