Should I skip sections pertaining to EU legislation? If so, which ones?
Like I said in the comment that somebody inexplicably removed, you should read the portions regarding EU legislation, in part because many enactments of UK law originated from EU Directives and Regulations which the UK as [former] member of the European Union had to implement. This edition reflects that reading those portions does not make much difference in terms of pages anyway.
Years of EU legal precedents might have permeated UK case law and/or the UK judiciary's statutory interpretation, and EU laws most likely will keep having an impact on UK law because of the subsequent treaties and agreements both parties foreseeably will sign with each other. Even if the UK Parliament thinks a full legislative dissociation from EU laws is productive, it would take several years for the ensuing repeals and replacements to reach completion.
Furthermore, the acquaintance with EU legislation you would gain from reading those sections is likely to enhance your understanding of UK law. That is because comparisons of two or more systems leads to awareness of aspects (in this case, about UK law) that might otherwise go unnoticed.
