Peter is a specialist criminal lawyer practising in the most serious of crimes, usually murder.

He has expert knowledge of firearms and the legislation surrounding them, ensuring that he is always in high demand. He has long experience of prosecuting and defending serious violence, gang-related offending, drugs matters and matters involving allegations of dishonesty.

He has experience of fatal road traffic matters and a particular interest in environmental and wildlife crime. He has recently prosecuted a water utility company for polluting a water course, on behalf of the Environment Agency, prosecuted a National Crime Agency case involving the unlawful export of eels with an eventual value of some £53M and defended numerous other wildlife related offending.

He has enormous experience of defending service personnel before the Court Martial and is considered a specialist in military law. 

Away from work, Peter is usually found enjoying the British countryside or in the kitchen.

“One of the most charming and likeable barristers/opponents I have come across in recent times. Peter is a minister for justice in the true sense of the word, both fair minded but with equal vigour in his presentation of the prosecution case. A down to earth approach which makes it hard to defend against because he is immediately liked by both juries and judges. His witness handling of frightened bystanders was a joy to watch and he is, in my view, a first class barrister. I would very much like to defend with him too where he will doubtedly demonstrate his flair in a defence context.” – Legal500 2022

“Pre-eminent practitioner in cases concerning firearms licensing and wildlife crime who is applauded for the depth of his knowledge. He regularly provides regulatory advice and defends private clients who have breached firearm licence requirements.”

“Easy to work with, accessible and very knowledgeable about firearms.”
