Sonn Macmillan Walker

The team at Sonn Macmillan Walker has a strong focus on high-profile extraditions to a large variety of countries as far afield as Kuwait and Armenia. Outside of extraditions, the practice is often instructed on cases involving Ponzi schemes, murders, sexual assault, and class A drugs. The team is led by David Sonn, Katy Smart, and Amy Cox. Smart oversees the extradition team; she regularly advises politically exposed individuals for INTERPOL representation. Cox, ‘intelligent, compassionate and highly motivated to always achieve great results for her clients’, spearheads the litigation department. Leah Connolly, ’particularly expert at dealing with the young and vulnerable and their immediate family’, often defends youths on charges of murder and attempted murder.
