 The name was then transferred to a county constituency electing one MP from 1885 until 1918.

Notable MPs have included the regicide, Francis Allen.Until the Great Reform Act of 1832, the constituency consisted solely of the market town of Cockermouth in Cumberland.It first returned members to the Model Parliament of 1295, but its franchise then seems to have lapsed until 1641, when the Long Parliament passed a resolution (15 February 1641) to restore its ancient privileges.
