A deal between the European Union and Poland could see it becoming a bigger exporter of goods and services to the continent, as well as a significant buyer of UK goods.
The deal would also enable the EU to increase its influence in Polish politics, while the country would benefit from a reduction in tariffs and more access to the single market, the EU’s biggest trading partner.
Poland is also a major source of cheap labour for the UK, which imports more than a quarter of its products.
A similar deal between Britain and Ireland could also see Poles become a bigger market for UK goods in the future, helping to offset the UK’s decline in trade with the bloc.
Polish prime minister Andrzej Duda has also previously said he was ready to negotiate a deal with the EU, if the UK government’s Brexit negotiations were successful.
