The 7th dan Scotland and GB player and coach was awarded the gong for services to judo as part of the Queen’s Birthday Honours List in 2020, but only received it on January 19 due to a Covid-19 backlog.
He said he chatted with the Princess Royal for around five minutes.
He added: “She has a great sporting background anyway as a former Olympian and was interested in how judo was doing across the Commonwealth and how we were dealing with the challenges of Covid.”
He was joined at the ceremony by his wife Helen.
