Markus is known for his thoroughness and excellent client care. He has been commended by District Judges for his “persuasive points under pressure of time” and his “focussed” written submissions.


Before coming to the Bar, Markus worked at Advocate (formerly the Bar Pro Bono Unit). Here he worked on General Medical Council (GMC) cases with doctors facing allegations of manslaughter, drug trafficking, and serious sexual offences. He also worked on the first private prosecution under the Reserve Forces (Safeguard of Employment) Act 1985 and a child death inquest that led to the first prosecution of an NHS Trust for unsafe care and treatment.

Markus was also a paralegal with a Tier 1 London firm where he provided research and drafting support to senior partners in financial crime, extradition, and cross-border civil matters.

As a multilingual lawyer with training in diplomacy, Markus has a strong interest in international work. He was Junior Counsel in a People’s Tribunal concerning organ harvesting in China, for which he cross-examined a former Canadian Secretary of State. He also worked in research and advocacy roles at the International Federation for Human Rights (FIDH) in Paris and the United Nations Office for Drugs and Crime (UNODC) in Vienna.

Outside of his practice, he volunteers with the charity Bridging the Bar and the prison outreach team at his church.
