The London Swinton Circle (otherwise known as the Swinton Circle) is a long-running British right-wing pressure group. The group states that its purpose is to uphold traditional conservative and Unionist principles.
The group formed part of a number of Conservative Party-linked fringe groups which came to prominence in the 1970s and 1980s, such as the Monday Club, Tory Action and WISE (Welsh, Irish, Scottish, English), but is now positioned outside of the Conservative Party.
