David Harper has been appointed as Director of Intelligence and will be joining the Competition and Markets Authority (CMA) from the Metropolitan Police in December. His main responsibilities will be to develop and lead the CMA’s cartels intelligence team and to manage and develop intelligence-led investigations within the Cartels and Criminal Group (CCG). This will include building on the CMA’s existing relationships with partner agencies and ensuring the lawful deployment of the CMA’s investigation powers.

Emma Lindsay, who is currently an Assistant Director in CCG, has been appointed as Director of Criminal Enforcement. In her new role, which starts with immediate effect, Emma will be primarily responsible for the project direction of criminal cartel cases, developing with the lead investigator the case strategy and investigation plans and ensuring that cases are investigated and prosecuted lawfully, effectively and efficiently. Emma will also play a leading role on assessing criminal law and enforcement policy issues within the CMA.

Sonya Branch, CMA Executive Director of Enforcement, said:

Cartels cheat consumers and other businesses of getting a fair price and we are determined to crack down on them. With over half of new cartel cases opened since 2010 having been intelligence-led, the CMA is acting increasingly like a mainstream criminal enforcement agency. Our most recent activity includes the ongoing prosecutions in the galvanised steel tanks cartel case and successful prosecutions for unlawful pyramid selling under consumer protection law.

These 2 appointments are among a number of additional senior posts that we are creating as part of an investment in building up the CMA’s intelligence, investigation and enforcement capacity further. This will enable the CMA to increase both the number and speed of cartel investigations that we are able to pursue, both criminally and under the Competition Act 1998 (CA98).

David and Emma will join the existing cartels and criminal senior leadership team, comprising Stephen Blake as Senior Director – Cartels and Criminal, Lee Craddock as Director – Investigations and Criminal Enforcement, and Juliette Enser as Director – Cartel Enforcement, leading on civil cartel enforcement under the CA98. The group reports to Sonya Branch, Executive Director of Enforcement.

The CMA expects to appoint a Director of Digital Forensics and Intelligence shortly, and will be advertising a further number of cartel roles, at various levels, in the new year. These roles will be advertised on Civil Service jobs.
