In this job every day is different. That’s what attracted me to it and why I like it.  I’m always looking to work in new areas with new clients. There’s no typical day. I can be found as often in a Crown or County Court acting on last minute instructions as in chambers preparing a conference or drafting pleadings.

I’m always happy to talk through a problem as well as preparing a particular document or appearing in court. The law in our practice areas is constantly moving and outcomes are so fact-sensitive that every case needs a customised approach. You’ve got to be versatile.

Seeing a case from the Judge’s point of view was the most valuable experience I gained from the Deepcut Inquest. The Coroner had to piece together evidence from over a hundred witnesses and over 90 lever-arch files of documents. There were some great areas of difference between the experts and many directly disputed factual points. Ultimately whether a witness or an expert is more convincing than another one depends most of all on how they come across in court. That’s why the advocate’s role in questioning them can be so powerful.

As a student I realised I had a liking for public speaking. Bizarre, I know: It’s most people’s worst nightmare, but I chose my career so I could get paid for doing it. But in the job you quickly realize that the best way to help a client isn’t often about making a long speech whilst wearing a wig. Getting a result that keeps matters out of court can be just as satisfying as winning in front of a Judge.

I came to the bar via a History degree. I wrote my dissertation on Gandhi, who was once derided by Churchill as nothing more than a ‘seditious Middle Temple lawyer’. As it happens, Gandhi was called to the Bar at Inner Temple, but Churchill was never one for attention to detail. After all, he never trained as a lawyer.
