If you are interested in learning more I humbly suggest watching the documentary &quot;The UK Gold&quot;.  The trailer can be found here: <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=kXBJLH2xrBM" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=kXBJLH2xrBM</a><p>I&#x27;m in no way affiliated with the documentary but I do work in the Square Mile.  I always had a hint of these things but never really had to time to research it for myself and this documentary helped me to understand it and fill in the gaps.
