What the title says.
For me....
Current politicians:
David Davis (For having principles and being in favor of civil liberties)
Nigel Farage (Compared to most of the rest of his party, he's quite reasonable. He could do with keeping his mouth shut more often though
)
Damian Green (A decent liberal voice within the Conservative Party. There needs to be more of those.)
Kenneth Clarke (As Chancellors go, he was decent. Also possibly the most decent member of the current cabinet.)
Past politicians:
Michael Portillo (Post-1997, of course. The Tories really should have elected him as leader in 2001.)
Ann Widdecombe (I don't actually
like her, and her views even less, but at least she's honest about them.)
Harold Macmillan (I don't know if he counts considering that he'd probably be on the John McDonnell wing of Labour nowadays.
Lol, jk of course.)
Edward Heath (Yeah, another obvious choice I suppose.)
