Helen Ralston-Smith

Helen has 15 years of professional experience in applying economic principles to issues of strategic importance for businesses, predominantly in the context of litigation and competition investigations. Much of her work has focused on high-profile cases such as the European Commission’s investigations into foreign exchange trading and government bond trading, as well as national competition and regulatory authority investigations into parity clauses and allegations of excessive pricing.

She has also presented oral evidence to the European Commission and the CMA, as well as to international regulators and authorities such as the Australian Competition and Consumer Commission and the Mexican competition authority.
