Louis St Laurent was a life-long Liberal, from a Liberal family (his father having been a candidate in some election or another). He had, however, no practical experience when, in 1941, Ernest Lapointe, King's powerful Québec lieutenant died, and he (St. Laurent) was persuaded to come to Ottawa â “ only until the end of the war. In that respect he was an outsider.
St. Laurent was a brilliant man â “ turned down a Rhodes Scholarship, etc â “ and was an internationally known barrister with friends in high places in London and Washington. That also made him something of an outsider in a Party which kepy close to its local roots.
He and Howe were a 'team' in managing the transition to peace and, especially (with Acheson), an active, leading role for Canada in reshaping the global multilateral institutions like the UN and NATO.
His first, important 'break' with King and O.D. Skelton's foreign policy (which St Laurent repudiated, wholly and completely) was over Korea, in 1949; there were many more: mostly opposed by wings of the 'big tent' Liberal Party which we would recognize 60 years later. St Laurent was a skilled, 'natural' politician: able to build coalitions and scatter opposing alliances through a combination of legal/argumentative skills and personality (there were no skeletons in his closet, he was 'bomb proof' on most traditional political fronts â “ that, too, made him something of an outsider).
