G7 Sherpas

Here is a list of the G7 Sherpas.

As the Sherpas are not usually politicians and are civil servants, their appointments are not always announced and their contact details are difficult to find. The State of Change tries to keep on top of the changes to ensure the list is up-to-date but cannot verify all the details are correct. The email and postal addresses can be accessed here  – this is subscriber only access, to subscribe to this State of Change channel, click here.
