Radical Action was a political group within the British Liberal Party. It advocated for liberal candidates to stand in elections despite the war-time truce. The organisation was founded in 1941 as the Liberal Action Group. It included some prominent members of the Liberal Party who disagreed with the war-time electoral pact in which the Liberals, Conservative Party and Labour Party agreed not to stand candidates against each other. Initially, its leading figures were Lancelot Spicer, Honor Balfour and Everett Jones, while Philip Fothergill became treasurer and Donald Johnson was the first chairman.
