His arrival boosts the number of Pinsent’s partners in the Asia-Pacific region to 12 partners and 40 lawyers.
Irvine’s hire is part of a plan to grow the banking and finance team across the firm, and the department now has 15 partners.
Last month Pinsents hired projects ace David Nash from Shepherd & Wedderburn.
Asia senior partner John Bishop said: “We are responding to client demand by developing our finance and corporate capability.”
