But only by exclusion. The Economist speaks from a classical/neo liberal viewpoint. Civil liberties, free markets, laissez faire, technocracy. Labour is too statist for them, and the Conservatives are currently too populist (and incompetent). The Economist's position lines up pretty well with the Orange Book wing of the Lib-Dems [1], but much less well with the SDP / social liberal wing.

They have backed all three major parties in general elections in the last twenty years [2].
