# Another, common usage, denotes the ideology of [[w:social-democracy|social-democracy]], as defended by the [[w:Liberal Party (UK)|Liberal Party]] in Britain, particularly since [[w:Lloyd George|Lloyd George]]'s [[w:People's Budget|People's Budget]]. It is with this background that [[w:John Maynard Keynes|Keynes]], though influenced by [[w:Fabian Society|Fabianism]], claimed to be liberal in the 1930s.
