High-profile barrister Cherie Blair has announced she is to leave the barristers chambers she helped to start 14 years ago.

The QC has decided to leave Matrix Chambers to focus on her legal advisory practice Omnia Strategy, of which she is chair, a statement from Omnia announced yesterday. 

Blair will also continue to work independently as an international arbitrator.

She said: ‘Omnia Strategy was born from a recognition that clients often wanted more than legal solutions to complex problems. What makes Omnia unique is the holistic and strategic approach that we offer to clients who are facing complex issues where matters of law, business, policy and communications all overlap.’

The firm was founded in 2011 and received an alternative business structure licence two years later from the Solicitors Regulation Authority.

It offers advice to governments, multinational companies and private clients in private and public law, international dispute resolution and strategic communications.

Rhodri Thompson QC, chair of the management committee at Matrix, said: ‘We are of course sad to see one of our original leaders leave the organization that she helped to create. Since then, Matrix has established an outstanding reputation both domestically and in an increasingly global legal market.’
