Before taking silk in 2022, he was nominated by Chambers & Partners for the Junior of the Year award for Commercial Litigation in 2018, and for the Banking award in 2021. He was also identified in Legal Week’s ‘Stars at the Bar’ 2012, which noted his “interpersonal skills and clear professional acumen”. Interviewees commented that he is “an invaluable member of every team he’s on” and “his written work is absolutely first rate, [articulating] even the most complex of arguments in a style that is both pithy and persuasive”.
