UK Law Post-Brexit

Instruction  
Question: Critically assess the sources of UK law post-Brexit
Your assessment should be 1,500 words in length, including footnotes.
NB: The bibliography is NOT included within the word count. However, footnotes ARE INCLUDED within the word count.
The word count is 1500. There is a 10% leeway permitted if needed, thus you may exceed the word count within said 10% without incurring a penalty. For the avoidance of doubt this amounts to NO MORE than 1650 total words.
