Moore was known for his conservative political views. In the 1970s, he was chairman of the anti-immigration United Country Party, a position he held until the party was absorbed by the New Britain Party in 1980. He campaigned for the politician Edmund Iremonger at the 1979 general election, as they agreed the French and Germans were not to be trusted. Iremonger and Moore gave up political campaigning after deciding they were Thatcherites. Moore campaigned on behalf of Douglas Denny (UKIP) for the Chichester constituency in 2001. A Eurosceptic, he was a supporter and patron of the UK Independence Party.
