A Word From Our Chair

Having been involved in a number of ThoughtLeaders4Disputes events, I have always been impressed by the quality and range of knowledgeable speakers they are able to assemble for their conferences. This makes for a lively and informative discussion. Their decision to now expand in to Competition Collective Actions is therefore very exciting. The subject matter is highly topical, with competition collective actions taking off in the last couple years and now representing some of the most high profile and largest disputes before the English Courts. There is much learning to be shared, and ThoughtLeaders4Competition will no doubt bring together an impressive array of speakers to their events.
