Simmons & Simmons’ London corporate practice is to see two partners depart, with Gavin Weir set to leave next month to join White & Case, while US securities partner Daniel Winterfeldt (pictured) quit the firm in December.

Weir will formally leave Simmons at the end of February to become the ninth M&A partner in White & Case’s London office. He has been a partner at Simmons since 2006, when he joined from Allen & Overy.
