The European Union is very active on many fronts. The best way to keep up with fast-moving developments in the EU is to use the Europa website of the EU, and in particular, its Newsroom section.
Another way to track developments in the EU is again to use the Europa website of the EU, but this time for the purpose of linking through to the websites of the various European institutions. For example, if you click on Institutions and bodies of the European Union, you go to a page with links to each of the institutions. Continuing the example, you then click on the link to the European Commission. There you have a link to each of the Directorates-General that make up the Commission. At the page for each Directorate-General, you will find a News link.
