This year marked the three hundredth anniversary of the Treaty of Utrecht, under which Spain permanently ceded Gibraltar to Britain (it was following the end of the War of Spanish Succession). At least they can't claim, like Argentina with the Falklands, that they never gave it up.
Now the Spanish are threatening to charge £85 for a border crossing. So a European country is charging for the movement of goods and people but only to one nation - The Portuguese and French get in free of charge.
If this is permitted surely it marks the end of the European Union. Surely?
