Jagoda practises in public, commercial and competition law, and has been named as a “Rising Star” in administrative law and human rights by Legal 500. She has been instructed on high profile cases in each of those practice areas, and regularly appears in court for claimants and defendants. She has appeared in cases listed in the Lawyer’s Top 20 cases for three consecutive years, and this year also appears in the Lawyer’s Top 20 appeals. Notable recent instructions include:

  • Al Haq v Secretary of State for Business and Trade: appearing for the Claimant in a judicial review challenge to the export of F-35 fighter jet parts to Israel following the military invasion of Gaza after 7 October 2023 (led by Phillippa Kaufmann KC, Raza Husain KC and Blinne Ní Ghrálaigh KC) (one of the Lawyer’s Top 20 cases for 2025)
  • Johnson v FirstRand Bank Limited: acting for the Financial Conduct Authority as intervener in this Supreme Court appeal concerning the payment of undisclosed commissions in the motor finance industry (led by Jemima Stratford KC) (one of the Lawyer’s Top 10 appeals for 2025)
  • Athena Capital Fund and others v the Secretariat of State of Holy See [2025] EWHC 355 (Comm): acting for the Vatican in a fraud trial concerning an allegedly overvalued London property sold to the Vatican, related to the largest criminal trial in the Vatican’s modern history, in which one of the claimants has been convicted of embezzlement and sentenced to 5 years in prison (led by Charles Hollander KC, Samar Abbas Kazmi and James Bradford) (one of the Lawyer’s Top 20 cases for 2024)

Jagoda is equally comfortable led in a team of counsel on large, significant matters, and acting as sole counsel – she has appeared unled in the High Court, county courts and various tribunals.

She is also committed to a pro bono practice and was shortlisted for Young Barrister of the Year at the Bar Pro Bono Awards 2024.

Jagoda holds first class degrees from King’s College London (LLB) and the University of Cambridge (LLM). Prior to coming to the bar she worked in various research assistant and paralegal roles, including at the Law Commission of England and Wales and at the Lauterpacht Centre for International Law. She holds 14 awards and scholarships.
