Overview

Daniel joined Chambers in October 2025 following the successful completion of his pupillage. During pupillage, he was supervised by Madeline Stanley, Victoria Webb, Cristopher Edwards, and Jack Mitchell.

Daniel has experience in and accepts instructions across all of Chambers’ core practice areas. During pupillage, Daniel gained experience in a wide range of employment, personal injury, clinical negligence, and public law work. He regularly appears in the County Court and Employment Tribunal. He is particularly interested in collective labour law and EU law and has a niche specialism in social security law.

Prior to coming to the Bar, Daniel worked at the Free Representation Unit (FRU) as a Legal Officer. He regularly represented claimants in employment tribunals across the entire spectrum of employment claims, including discrimination, whistleblowing, TUPE, and holiday pay. He also regularly represented appellants in social security appeals, including complex EU social security coordination cases, as well as criminal injuries compensation, war pensions and industrial injuries benefits appeals. Alongside a busy caseload, he also supervised FRU volunteers running employment and social security tribunal cases.

Daniel has already gained experience of led and unled appellate work in the Employment Appeal Tribunal and Upper Tribunal (Administrative Appeals Chamber), such as Hilton Food Solutions Ltd v Wright [2024] ICR 862 (re: scope of unfair dismissal protections for parental leave), Secretary of State for Work & Pensions v NJ (ESA) [2024] UKUT 194 (AAC) (re: test for temporary absences from GB for medical treatment, currently under appeal to the Court of Appeal), and Matondo v Kingsland Nursery Limited [2024] EAT 123 (re: approach to corroboration of evidence). He is currently instructed in a discrimination challenge to provisions of the Housing Benefit Regulations as they applied to EU migrant workers pre-Brexit.

Previously, Daniel worked as a housing and welfare benefits caseworker at Z2K, the anti-poverty charity, and at South West London Law Centres, as well as voluntary experience at UVW, FRU, Liberty, CAB, and the Prisoners’ Advice Service.

He is a FRU trustee.

Daniel speaks Swedish (bilingual), intermediate Italian, Russian, and French, and basic Ukrainian.
