Should i study English or History at uni?

You have misunderstood how "job prospects" work in terms of degrees; nobody cares what specific subject you studied. Nobody. Unless you are going into teaching or academia, it's irrelevant (outside of STEM fields anyway); what employers look at/for are the transferable, "soft skills" the degree engenders in e.g. organisation, writing to deadlines, coping with pressure, written and oral communication ability, research skills, etc. English literature and History by and large develop the same kinds of skills so either will suffice for the same kinds of roles.

More important than you degree subject is making a point of getting relevant work experience/placements/internships during your degree course. I also don't see how English literature is more relevant to publishing; you aren't analysing the literary devices of the books your company is publishing, you are working in the business of publishing. Hence, what is important are the transferable skills, which as above will be the same between English and History for the most part. As such, you should pick the one you are more interested in, as it's more likely that interest will sustain you to getting a good 2:1 or a 1st.

As you've said already that you are genuinely interested in history, and you think the modules listed for typical history courses are more appealing to you, the choice seems fairly obvious - go for history.
