Lawyers have welcomed the appointment of Mr Hermer.

Gerard McDermott KC said: “I have worked closely with Richard Hermer KC over the last four years. He is the KC I admire the most. This shows a huge commitment to the rule of law.”

Fellow Matrix member Matthew Ryder KC said Mr Hermer was a “superb lawyer who will bring experience, judgement and legal acumen to the role”.

Law Society president Nick Emmerson said: “The new attorney general has extensive international and domestic legal experience and has been involved in the legal task force addressing international crimes committed by Russia in Ukraine. This substantial experience will be exceptionally valuable for the role of attorney general.

“It’s crucial to acknowledge that transforming the justice system is a long-term project, requiring a collaborative effort. We look forward to working with Richard Hermer KC over the coming parliament and sharing the insight and experience of our members to rebuild our justice system, harness the economic power of legal services and ensure access to justice for all.”
