Varian Of course the PM if Malta would say that. If the other country's that are in the brink of exiting got wind of a reasonable deal for UK, they would be out of the traps like greyhounds.
The EU will lose a lot of income from the UK both in remittances and generated trade they will have to maintain their over cumbersome and overpaid administration with around 20% less income, as a result some things in the EU will have to suffer so of course they are miffed.
Malta has benefitted from EU membership, they have nice roads now, however their importance to the EU is more to do with their strategic military position than any industrial, manufacturing or financial expertise which other countries have to rely on.
