Irwin Mitchell has expanded its business legal services (BLS) division with a hat-trick of lateral hires, including Pinsent Masons litigation head Nigel Kissack.

Kissack, who moves to Irwin Mitchell as national head of commercial litigation, is joined by Squire Sanders intellectual property partner Alex Newman and former Brown Rudnick lawyer Kirsten Doherty, who moves as a consultant.

The moves are the latest in a string of hires for the firm's BLS team in 2013 to 10.
