Machinery of Government: UK-EU Relationship The Prime Minister (Boris Johnson) Responsibility for the United Kingdom’s relationship with the European Union, including oversight of the implementation of the trade and co-operation agreement and the withdrawal agreement, is being moved to the Foreign, Commonwealth and Development Office. The transfer of responsibilities to the Foreign, Commonwealth and Development Office aligns the UK’s European strategy and bilateral relationships with the Department’s diplomatic expertise, as we continue to build a new relationship with the EU and its member states as sovereign equals, underpinned by trade, our shared belief in freedom and democracy and co-operation on common global challenges.
