White & Case is working to renew its relationship in London with key client Deutsche Bank, after six partners with links to the client left the firm’s banking and capital markets practice in 18 months.

Since key relationship partner Mike Goetz quit for Freshfields Bruckhaus Deringer in March 2008, a further five partners linked with Deutsche Bank have left in London — putting the connection under strain. At its height the relationship was thought to be worth around $25 million a year to the firm’s London office.
