Brexit will impact Least Developed Countries (LDCs) as the UK leaves the EU. LDCs will lose trade preferences, leading to potential GDP decreases of -0.01% to -1.08%. This is because the UK will no longer offer duty-free access to their exports, affecting countries that rely on these benefits. The UK's exit from the EU will also impact trade agreements with developing nations, particularly in sectors like apparel, textiles, and sugar. The negotiations between the UK and the EU will have significant consequences for LDCs, highlighting the broader implications of Brexit beyond just the UK and EU.
