Pillsbury Winthrop Shaw Pittman is set to see at least eight partners leave for US rival Winston & Strawn, with the exits following the recent departure of New York partner Jeffrey Stern to Winston.

Eight partners have quit Pillsbury for Winston across New York, Washington DC and San Francisco, with the managing partner of the firm's Abu Dhabi office, Stephen Jurgenson, and London partner James Simpson also understood to be moving over. 

Both Jurgenson and Simpson moved to Pillsbury in 2012 from the now defunct Dewey & LeBoeuf in the midst of Dewey's wind down.
