Adler, a partner at Speechly’s for the past seven years and who joined Mishcon last week, is particularly well known for international matters, with a focus on Israeli and German-related matters.
He said he had known the Mishcons for several years but that the firm had “developed enormously” recently, particularly in terms of its corporate practice.
“The firm has always been entrepreneurial but I think it is a much more coherent group now,” Adler said.
Speechly’s managing partner Michael Lingens said Adler had been “a very valuable colleague over the years who has contributed greatly to the recent growth of the firm. We will be genuinely sorry to see him go and wish him well.”
