Brexit has led to increased exports of fruit and vegetables from the EU to the UK, but has also caused additional challenges such as traffic jams, congestion, and extra customs work. There are fears of delays due to the need for extensive import-export documentation and potential disorders in the supply chain. Trade associations are advocating for 'green lanes' on ferries to expedite the process. The agreement between the UK and EU has prevented tariffs and quotas, but there are specific rules for composite products and re-export. The movement of goods through the UK for export to Ireland is expected to continue, despite some uncertainties.
