Criminal Defence

Brian is instructed in criminal cases of the utmost gravity and seriousness by leading defence solicitors. His vast experience has earned him the respect of those who instruct him, his peers and the judiciary.

He is regularly instructed in high profile murder cases including the defence of a young man accused of four counts of murder following a revenge attack house fire.

He undertakes terrorism cases including the defence of a man accused of being part of a plot to blow up the Stock Exchange, and, the prosecution of two passengers accused of threatening to bring down a PIA plane on its approach to Manchester.

His instructions include allegations involving serious sexual offences where his judicial experience (he is authorised to try such cases in his capacity as a Recorder at the Central Criminal Court) gives him a distinct advantage.
