Peter Borrowdale joins the City firm's corporate and finance team in January. The move comes after US firm Sonnenschein closed its eight-strong London office at the beginning of this month.
Ironically, Warner Cranston and Sonnenschein were in merger discussions earlier this year, but the talks fell through (The Lawyer October 4).
Peter Alfandry, Warner Cranston's practice development partner says: "We are extremely happy that, with Peter Borrowdale joining us, the very good relationship that has been built up with Sonnenschein will undoubtedly continue."
As reported in The Lawyer last week, DJ Freeman has taken on four Sonnenschein partners.
