Linklaters disputes partner Mark Humphries is to leave the firm to launch his own litigation boutique in Bristol. The niche firm, which will be known as Mark Humphries, will also offer advocacy services. Humphries, who is acting for energy giant Centrica on its £182m claim against consultancy group Accenture, resigned from Linklaters in 2008 but has remained at the firm to complete ongoing work. The Centrica litigation is due to get underway in late June and Humphries will exit the firm in late July.
