Political career 
Dartmouth was returned to Parliament for Plymouth in 1778, a seat he held until 1780. The latter year he was returned for both Horsham and Staffordshire 1784, but chose to represent the latter. He continued to represent this constituency until 1784. From 1783 to 1798 he served as Lord Warden of the Stannaries.
