Ban political donations from sources outside of the UK

Background

Ban all donations to UK political organisations from foreign individuals or organisations; limiting foreign interference to the British political system and way of life.

Additional details

We need to protect our fragile political system from foreign external influence. An individual or organisation who doesn't live, or no longer lives in the UK, should not have the means to exert influence on British politics and, by extension, our way of life more than the poorest UK citizen. Any political donations should be subject to thorough KYC background checks to ensure the source is not from foreign sources aiming to change the political landscape from outside of the UK.
