Alistair Parker


Criminal law, fraud and regulatory/disciplinary

Ali qualified in 2004 and has worked at Brett Wilson LLP since 2016. He is a creative and enthusiastic lawyer and advocate, defending in all manner of criminal investigations and prosecutions including so-called regulatory prosecutions brought by Local Authorities and government departments.

Ali is a Recognised Practitioner for Crime in Chambers & Partners.


Ali also defends allegations of professional misconduct. He has represented solicitors, dentists, social workers and a final year medical student before their regulatory bodies.

Ali is a recommended lawyer for Professional Misconduct in the Legal 500, 2019 edition.

Ali is also a specialist in defending proceedings brought under the Proceeds of Crime Act 2002.

Ali firmly believes that defending you is not simply about waiting for a Prosecution case to emerge and then looking for holes in it. By the time of prosecution, extensive reputational and financial damage may already have been caused.

As well as looking for weaknesses in the case against his clients, Ali seeks to pro-actively support and verify his client’s own account of events. Ali finds that, far too often, the limited resources and experience of police and other investigators means that the simplest or cheapest outcome is reached. Alternatively, where the investigation is deemed ‘complex’, it can lead to months or years of stagnation, or be kicked into the long grass by police with barely any update as to what is happening, or why.

Frequently, Ali will attend the scene, locate witnesses, ensure the retention of CCTV, banking records and phone records, or personally check police documents for accuracy. These are particularly important steps where police (or previous defence lawyers) have failed to do them objectively, or at all. Ali may also challenge the limited or subjective ambit of the State’s investigation. Ali listens to his clients’ instructions and is determined that potential evidence that might support them is not missed or disregarded. Similarly, where the investigator has failed to gather key evidence expeditiously or objectively, Ali will ensure that the Court can either draw proper inferences from these failures, or hear relevant legal arguments.

Whether in criminal defence or professional discipline, Ali’s clients feel he is in their corner not simply as legal advisor and representative but also as an active investigator.

I would like to thank you once again for tirelessly and honestly advising and representing me this past 13 months. Without your expert counsel), I feel this would have all likely ended very differently. You brought an air of calm, organisation, and remarkable composure to what was an incredibly chaotic and distressing year for myself and my family. Your reassurance, but also unwavering honesty, helped me keep my sanity!

I would like to thank you for all your efforts in securing this outcome. Without all the work completed by my son and you I am sure we would not be in this position.

I acknowledge mine wasn’t the most challenging of cases for you, however for me it was much more significant. I am writing primarily to thank you for being a professional, and more importantly (for me), a human.

Regarding an assault matter, 2017


Ali is a most genuine and sincere man – he resolutely stood beside me and helped to give me belief that there would be a positive outcome for me. When the Police failed to respond he chased them and maintained superb contact with me following up and parrying the Police without irritating them. He has a warm kind and genuine heart, yet he is efficient and determined and extremely clever in knowing what and how to say things and what to include and leave out. He is the classic firm but fair individual and knows how to stand up to difficult situations and drive them forward. He guided me so well and all the time reassured me and showed immense care towards me and my wife and the situation foolishly I got myself into.

I would like to take this opportunity to thank you for not only your hard work and diligence on my matter but also your kind and thoughtful words of advice and encouragement which have not only kept me going but allowed me to keep my family life intact (it’s no exaggeration to state that both myself and my wife have been rather hysterical at times).  Your encouragement has also permitted me to run my business with a certain degree of confidence despite the best efforts of (the investigators) sniping away at my livelihood.

Thanks again for all your work, we really appreciate it.

Director of property company accused of regulatory offences by Local Authority. 2018.


It’s hard to find the words to thank you really, you did your job that you trained for and are paid for yes, but , I felt you went that but further for me. If you give all your clients this service I applaud you because for me it felt very personal, almost like a friend or brother was defending me. Your final speech in court really made me choke as it was not only addressing the law but it was heartfelt and powerful in delivery and I honestly could not have said it better myself.

I think that’s where you impressed me the most to be honest. How well you understood my circumstances and how I felt and how incredibly accurate you put it into words. Better than myself and I honestly struggle to put faith into anyone in my life as I do always believe no one can say and do it better than me. But you did. From the moment I spoke to you on the phone I felt confident and reassured that you absolutely were going to do everything in your power to get the result I deserved. And that you did and in style I may add.

Following acquittal on charges of harassment in the Magistrates Court.  2016

Following prosecution for harassment, 2017


You asked in your email if I would let you know what I thought. Well I thought I would let you know that I am truly happy at this brilliant statement you have put together for me, which gives an accurate account of that night. I think you have captured a lot of things that happened that night which ultimately lead to me being let down by people that were meant to protect me.

Again, I will be forever grateful for you taking me on as your client and helping me.

Many thanks again, I literally cannot thank you enough!
