  • Debate on proposals for a written constitution

    The UK is one of the few democratic countries that does not have a codified constitution. Instead, the UK has a set of constitutional arrangements contained in various statutes, judicial decisions, conventions and precedents. The prime minister, Andy Burnham, has said his devolution agenda strengthens the case for a written constitution. This briefing summarises some of the arguments that have been made for and against a written constitution.

  • UK-EU Agreement in respect of Gibraltar

    The UK and the EU have agreed a treaty that would create a new framework for Gibraltar’s relationship with the EU following the end of the Brexit transition period at the end of 2020.
