Margaret Thatcher and Ronald Reagan are examples of politicians that I mostly disagree with their views but I've never regarded them as personally dishonest.
Reagan secretly sold illegal weapons to Iran to fund bloody coups and death squads in South America. I’d say secretly committing treason is a pretty big lie.
Also worth noting is the October Surprise, where Reagan foiled negotiations with Iran to bring US hostages back, in order to help his election chances.
That's what I meant by "personally" honest - their governments they led had all kinds of problems but I don't think that was caused by fundamental dishonesty by those individuals.
