It's a new year and a new chapter for the UK's relationship with Europe. How millions of people live, work and travel will look very different in 2021. That's because the transition period - when the UK continued to follow the EU's rules - ended on 31 December. Now a post-Brexit trade deal, reached just before the deadline, has come into force. So, with this historic change looming, the AFP spoke to Europeans in the UK, and British people in Europe, about what Brexit could mean for them. Catalina-Anca Toader from Onesti, Romania... now living in London I came to the UK more than five years ago when I was accepted by the University of Westminster. I graduated with a first-class degree in 2018, and now work for a digital advertising agency in London. I hold settled status and plan to apply for UK citizenship in 2021. During the Brexit negotiations, I was concerned about the exchange rates as well as potential longer queues at airports. But I was mainly worried about whether the UK would impose stricter rules for citizenship and if my student loan repayments would be affected. I was ultimately left counting down the days until the end of the transition period, worrying that the UK and the EU wouldn't reach an agreement. So I'm happy with the deal at this stage and, hopefully, I'll soon be able to have dual citizenship. But I do think people may need more time to prepare for the sudden changes. Jason Carter from the UK's Isle of Wight... now living in Stockholm, Sweden I first arrived in Sweden as a student in 1999. I met my wife, Jessica, in Stockholm around that time but only moved here permanently in 2006. I live here with Jessica and our 11-year-old son, Ulf. I became a Swedish citizen in 2016 and have dual citizenship. I applied in April ahead of the Brexit vote because I wanted to ensure I remained an EU citizen afterwards. As someone whose life has been altered by the opportunities and rights that being a member of the EU gave, I was concerned what would happen to those rights. In particular, the right for my family to resettle in the UK one day. When I married Jessica we both had the right to live and work in the UK or Sweden. Any attempt to return to the UK would likely be extremely difficult now - so the future we had planned is now no longer easily available. I had also hoped that my son would one day be able to spend time on the Isle Of Wight, working summer jobs and living in the UK. But this is not as easy as it once would have been. I don't think this is the deal that anyone wanted. But the fact a no-deal Brexit was averted at the 11th hour is perhaps more of a cause for celebration.
