Described as “a brilliant and balanced advocate” and being “exceptionally bright, able, independent-minded and thorough“, Angus is recognised as one of the leading KCs at the Bar across a range of different legal fields, with a particular strength in written and oral advocacy. In the Legal 500 2021 guide, clients described Angus as “undoubtedly the leading Special Advocate – the silk of choice in any national security or fair trial issue.”

Angus McCullough KC has extensive experience in matters of public and private law on behalf of individuals, private bodies, Government departments, and other public bodies. He has been appointed to act as amicus curiae (advocate to the court) on many occasions, including in the phone hacking trial of R v Rebekah Brooks et al and committal proceedings against Stephen Yaxley-Lennon (aka Tommy Robinson). He has appeared in the Court of Appeal, the Supreme Court, as well as representing the UK Government at the UN in Geneva and in European Court of Human Rights in proceedings in Strasbourg. He has acted in 9 cases before the House of Lords / Privy Council / Supreme Court.

He conducts medical claims of the highest value and complexity for both claimants and defendants. He won the Chambers and Partners award for personal injury and clinical negligence barrister of the year 2009, took silk in 2010, and medical law remains a major specialism. Angus is available to act as a mediator in personal injury and clinical negligence disputes, bringing his extensive experience acting for both sides in the field to facilitate resolution. He also advises and appears in regulatory and disciplinary matters.

Angus has been instructed as the special advocate in some of the most high profile cases of recent years in the field of national security, and has been active in promoting understanding and debate in relation to closed material procedures.

He was appointed as amicus in the phone hacking criminal trial of R v Rebekah Brooks and others, to advise the court in relation to reporting restrictions and costs.
