Di Middleton


Di Middleton QC is an experienced criminal defence barrister who, as leading and junior counsel, has been instructed across the full spectrum of high-level crime including murder, serious violence, controlled drugs, fraud and serious sexual allegations. She has extensive experience of cases involving intelligence led investigations, specialist operations and covert surveillance.

She was appointed Queen’s Counsel in January 2017 and formally became a silk when she made her declaration before the Lord Chancellor at the ceremony on Monday 13 February 2017.

Di is known for her assiduous close analysis in high-volume cases including those which involve special procedure material, forensic audio and visual material, and expert scientific evidence. She is also highly regarded for her tactical acuity in cases involving multiple defendants, cross-allegations and “cut-throat” defences.

Di is frequently instructed in cases which involve vulnerable defendants and witnesses. Having spent several years as a secondary school teacher prior to her career at the Bar, she has a proven ability to gain the trust of even the most justifiably self-protective juvenile defendants in order to successfully represent them in criminal cases of upmost gravity. Due to her extensive familiarity with cases involving fitness to plead, hospital admission and serious sexual allegations, she is frequently counsel of choice in cases where witnesses or defendants are vulnerable due to age (very young and very elderly) or mental illness.

Di is ranked for Fraud in the Legal 500 2016.

“She appears in confiscation proceedings and challenging fraud trials.”
