Depends how far you are into your studies.
You say you are doing a BA in International politics. 3 years?
- You can't be a fresher otherwise your course will only just have started.
- If you have passed part II & are entering your final year and asking us if you should bother finishing a degree when you have only 8 months to go, then you deserve a slap.
- I assume then that you have passed Part I and are starting part II?
The Bologna Process means your degree will count for as much as any Finnish Bachelor's degree in a few years time.
I would say that in terms of getting a job (a decent job, not picking berries), having a degree is quite important, in case of applying for a job if there are two similar candidates up for the same job, I'd rather be the one with a degree than without.
I'm not in a recruiting position, but occasionally get asked opinions about whether someone is suitable for employment. I don't like quitters. You don't want holes in your CV and need to explain them away with... "yeah well, I heard that there wasn't much point in finishing my BA as I was coming to Finland" <---- not good.
If you can transfer your studies to Finland that might be an option, personally I'd complete in the UK then move here, if you are of standard UK student age then you will have a BA at 21, pretty much the same age as many Finns are after completing their fresher year.
