The proliferation of trade in services groups and coalitions originated with American Express in the US and British Invisibles in the UK. Key people such as Harry Freeman from AmEx and Leon Brittan and Andrew Buxton from BI and Barclays Bank were active in forming and leading these coalitions, which had a close relationship with each other and overlapping memberships.
All these business coalitions work closely together for similar goals which is perfectly understandable given their common origins and overlapping membership and leadership. For example, FLG press releases include contacts from CSI, British Invisibles and ESF. CSI and IFSL continue to jointly administer the group. In fact CSI has a hand in all but the European-based LOTIS groups and the ESF. The ESF nevertheless works closely with the CSI and has a similar, if less strident, agenda.
