Carney may replace Tupper as Canada’s shortest-serving prime minister

He maintained his cabinet post even after moving to London, England, in 1883 to become the unpaid Canadian High Commissioner to the United Kingdom. Tupper surrendered his seat the following year, but Macdonald wooed him back for a successful 1887 election bid and handed him the finance portfolio. Within 18 months, he resigned and returned to London and stayed there until 1895.
