Answer 2

The main reason other members of the EU are concerned about the British decision to leave the EU is because it could potentially lead to other countries following suit, which would undermine the unity and stability of the bloc. Additionally, Brexit could have economic and political repercussions for the EU as a whole, as Britain is one of the largest economies and a key player in foreign policy and defense. Brexit negotiations have also highlighted divisions among EU member states, particularly in regards to issues such as migration and sovereignty.
