Emmanuel Macron has warned fellow European leaders to remain focused on their “collective interest” during Brexit negotiations lest an “unfavourable situation” befall the remaining 27 EU members.
The French President said the continent could suffer if individual countries used Brexit to follow their own interests and that states must avoid the “prisoner’s dilemma”.
In the famous game theory scenario, two people act for their own gain and both lose out even though they pursued an apparently rational course of action.
Macron is worried that as various European countries might want different things from us after Brexit, the false front of unity within the EU will crumble as each one aims for the best deal for itself.
He's frightened that if one country steps out of line on the claimed 'unified' approach others may follow and the whole of the EU will suffer.
