Biography

Devious and untrustworthy

An intellectual figure credited with establishing some early reformist ideas, Shelburne was less appreciated in his own time, being considered devious and untrustworthy.

In the 1760s he spent two years as Pitt's Secretary of State, and in the late 1770s led the Whigs in Opposition. On Rockingham's death in 1782, he formed a government as PM, with the 23-year-old Pitt the Younger as his Chancellor.

During his short term he succeeded in securing peace with America, France and Spain, presided over the beginning of Britain's trade recovery, and put forward a programme of public service reform.
