“I have not come across many for her call with such an appetite for success.” – Solicitor, Head of Criminal Department

“You conducted yourself with a confident poise both in and out of the courtroom and argued the case to the jury with formidable intellectual conviction. Your preparation was thorough, your explanations accessible, your patience inexhaustible, and your trial strategy flawless.” – Lay client

Prior to pupillage Olivia was a paralegal for a leading international crime and extradition barrister assisting on cases before the European Court of Human Rights in life without parole cases, applications for the removal of INTERPOL Red Notices, submissions to the FCDO for sanctions breaches, and Part 2 Extradition cases.
