evidence: The deal contains new rules for how the UK and EU will live, work and trade together. [...] Northern Ireland will continue to follow many of the EU's rules in order to avoid a hardening of its border with the Republic of Ireland. This will mean however that new checks will be introduced on goods entering Northern Ireland from the rest of the UK. Now that it's no longer in the EU, the UK is free to set its own trade policy and can negotiate deals with other countries. Talks are being held with the US, Australia and New Zealand - countries that currently don't have free trade deals with the EU.
