BSc in Pharmacy work in ireland?

[little one]

Is it possible to work as a pharmacist in Ireland with a BSc? Or will I need a MPharm?
I am doing a 4 yr MPharm degree, but if I finish after 3 yrs I will leave with a BSc. Will I still have to do a pre-reg? If I do, would it have to be in the UK? Or could I do it in Ireland? What are the differences in the two systems? I am looking into moving back to Ireland. Any help is greatly appreciated. Thanks.

If you want to work in the Republic of Ireland you will need to have completed a 4-year degree, i.e. the full MPharm, and your pre-reg and register in the UK before you can apply to register with the PSI. Sorry no short cuts.

Not certain about NI but pretty sure it's much the same.
