We are delighted to announce that Rhiannon Sara Crimmins KC has joined the Garden Court Chambers’ Crime Team.
Rhiannon is an extremely experienced, highly committed and fearless criminal defence practitioner.
Over her career, she has been instructed in over 50 murder trials and regularly defends those accused of terrorism, firearms, ‘gang’-related crime and fraud.
Rhiannon has developed an impressive reputation across the board, being described by lay clients as “outstanding”; by her instructing solicitors as “a leading light in her profession”, and by the Judiciary as “first class”. It is hardly surprising, therefore that she is consistently instructed in high profile and unusual cases that generate considerable media interest.
Rhiannon puts client care at the heart of her practice. She is particularly approachable to lay and professional clients alike and regularly complemented by lay clients for her down-to-earth approach and fearless commitment to those she defends. She is particularly adept in cases with religious and cultural sensitivities, as well as those defendants who are considered vulnerable – she considers that her past expertise in human rights and immigration law, appearing in the High Court and Court of Appeal, has provided her with an excellent foundation in this regard.
She has instructed in cases hitting the headlines, including the R v Tokosi [2025] attempted murder case, R v MS & Anr [2021] terrorism case and the R v B & Ors [2018] Ponders End shooting.
Rhiannon is ranked in the Chambers & Partners and Legal 500 Bar Guides as a Leading Silk in Criminal Defence, with testimonials describing her cross-examination as “meticulously prepared and skilfully deployed” and stating “everyone in the room wants to engage her because of her leadership and charm”.
