Experience of public and independent inquiries. For example:

  • Currently acting as lead counsel of a large team for British Gymnastics, the regulatory body for gymnastics in this country, in an independent review into coaching abuses (The Whyte Review).  This concerns complex issues of safeguarding, data access, regulatory mechanisms and responses, evidential requirements, and submissions.

  • Instructed by core participants in four complex strands of investigation before the Independent Inquiry into Child Sexual Abuse (IICSA) covering the protection of children outside the UK, Accountability and Reparation and Lambeth Council corruption. 

  • Represented the Child Migrants Trust, a small charity protecting the interests of British children migrated to the Colonies between the 1940s and 1970s without parental consent and into conditions of sexual abuse and often conditions amounting to torture and slavery.  Secured an acceptance of responsibility for these children, now elderly people, by the UK Government.  A compensation scheme was set up following the recommendation of the Inquiry. 

  • Represented the British Council in the investigation into the sexual abuse overseas of children by British nationals, or ‘sex tourism’. The Inquiry’s report was published on 6 January 2020. This concerned the laws available to prevent sex tourism, and of the debarring and vetting schemes available to employers overseas to detect applications for employment with children of people with a history of sexual and other offending.

The intervention focused on international obligations and inquiry independence.
