On the final day of my visit I addressed The Chicago Council on Global Affairs, who invited me to speak on the implications of Brexit for Europe, the UK and Wales.
Ar ddiwrnod olaf fy ymweliad, cefais gyfle i annerch Cyngor Chicago ar Faterion Byd-eang, a oedd wedi fy ngwahodd i siarad ynghylch effaith Brexit ar Ewrop, y Deyrnas Unedig a Chymru.
