A Client

Jill is a partner in Kingsley Napley’s Financial Services Group and has an extensive track record in advising firms and individuals facing regulatory and criminal investigations by the Financial Conduct Authority (FCA).  Having recently returned from a 12 month secondment at the Criminal Prosecutions Team at the FCA, Jill has particular insight into the organisation’s approach to the investigation and prosecution of serious financial offences.

When a regulated firm discovers an internal fraud or other misconduct which may have regulatory implications, it is important that swift and decisive action be taken to address the issue and to satisfy the regulator that all appropriate action has been taken. Jill has particular expertise in advising firms who are, or who may be, under the scrutiny of the FCA and in taking a proactive approach to head off potentially adverse action.

Jill also advises individuals applying to be FCA approved persons as well as those whose approved status is at risk.  She has experience in taking cases before the FCA’s Regulatory Decisions Committee (RDC) and Upper Tribunal.  She has advised upon applications to vary or revoke prohibition orders and assisted financial professionals in  retaining their regulated status and maintaining their careers in the sector.

She has vast experience in advising individuals who are facing investigation and / or prosecution by the FCA, as well as those who are invited by the regulator to attend compelled interviews in connection with on-going investigations.  She has particular expertise in representing those being prosecuted for insider dealing, including two clients who faced insider dealing charges in large, complex prosecutions.  Both were acquitted on all counts.  Jill also advises those being investigated for market abuse, criminal market manipulation and offences under the Financial Services and Markets Act 2000 (FSMA).

More generally, Jill has a broad fraud practice and has involvement in many of the largest Serious Fraud Office (SFO) investigations.  She has advised many individuals, both overseas and in the UK, facing section 2 / compelled interviews by the SFO, and ensuring that they are fully supported throughout that process.

Jill has considerable experience in conducting internal investigations on behalf of corporates, public authorities and other organisations, with particular experience in the regulated financial sector. 

Cyber-crime forms an increasing part of Jill’s practice.  She specialises in advising individuals and corporates facing investigation or prosecution for cyber-related offences, including computer-enabled fraud, malicious communications, data protection breaches and other forms of computer misuse.  She also advises those who have been the target of such activity and who wish to report the matter to the appropriate law enforcement agency.  Jill has written and spoken widely on cyber-crime and has a particular interest in the regulatory and criminal aspects of cryptoassets and Initial Coin Offerings (ICOs).
