Re: EEA requires an EFTA membership
@Jess, No. While UK can join EFTA a membership of EEA requires a agreement between EU commission and EFTA states. Currently new EEA states are only added on the EU side (EU membership does not mean automatic EEA membership, the EEA agreement is updated as new EU members join).
EEA members are also required to adopt EU laws in everything except.
1. Agriculture.
2. Customs union.
3. Euro.
4. Other issues that might not fall under the EEA agreement.
Everything else, this includes Schengen has to be adopted into laws of EEA member state. This does not happen automatically as is the case with full members of the EU. EEA member also don't have any say how EU set it's laws and makes decision.
For UK to re-join EFTA and then join EEA would making leaving the EU a pointless act for UK.
