Wider reading suggestions for Law

Hi im applying for Law at oxford, Bristol, Nottingham and Warwick.
Im interested in the philosophy behind the law and the implication of theories like utilitarianism on the law. I'm trying to write my personal statement but It's really hard to find wider reading based on my interests (which makes me think damn am i more suited to a philosophy degree over a law degree?)
Does anyone have any wider reading suggestions? related to this topic? (Books, podcasts, articles etc.)
Thank you so much
