Why are the EU at the G7?

1. The EU has regularly taken part in all meetings since the G7 Summit in Ottawa in 1981.
2. It never holds the Presidency, therefore never organises a summit. 
3. However, the 2014 G7 Summit was hosted by the EU in Brussels on account of Russia’s membership having been suspended. This was because Russia originally held the G8 Presidency that year. 
4. As one of the world’s most powerful economic areas it is important that the EU takes part in the G7 process. Another factor is the EU’s increased security policy commitment.
