Lachlan accepts instructions on a private basis and has a particular interest in white collar crime and related POCA proceedings.

Prior to focusing on criminal law, Lachlan had a varied common law practice, with a particular focus on business and property and housing. He has appeared in most courts across England and Wales, including the Business and Property Courts and the Administrative Court. As such, he is a flexible advocate who is adept at tailoring his submissions to meet the case and tribunal. This background sharpened his legal research and written advocacy abilities.

Lachlan is comfortable working with public bodies, having been seconded to a local authority’s housing department for a number of months in 2021.

In 2023 Lachlan was a ‘junior junior’ counsel to Undercover Policing Inquiry. The purpose of the inquiry is to get to the truth about undercover policing and provide recommendations for the future. Through this experience, Lachlan has an excellent knowledge of the Inquiries Act 2005 and of how to handle sensitive information.”
