The Communist Party of Great Britain is a political group which publishes the Weekly Worker newspaper. The CPGB (PCC) claims to have "an internationalist duty to uphold the principle, 'One state, one party'.

It is not to be confused with the former Communist Party of Great Britain, the Communist Party of Great Britain (Marxist–Leninist), or the current Communist Party of Britain.

The British left can refer to multiple concepts. It is sometimes used as shorthand for groups aligned with the Labour Party. It can also refer to other individuals, groups and political parties that have sought egalitarian changes in the economic, political, and cultural institutions of the United Kingdom. There are various subgroups, split between reformist and revolutionary viewpoints. Liberals, progressives and social democrats believe that equality can be accommodated into existing capitalist structures, but they differ in their criticism of capitalism and on the extent of reform and the welfare state. Anarchists, communists, and socialists, among others on the far left, on the other hand argue for abolition of the capitalist system.
