The latest buzzword seems to be 'sovereignity', which we are supposed to have lost.
That is really taking us back to the days of Empire when Britain ruled the world. Since then we have made deals and pacts and agreements with loads of countries, without losing our autonomy. And done very well out much of it too.
It is on a par with 'taking back control'. While in the EU we have a great deal of control, after Brexit we will lose any influence we have with our closest neighbours and trading partners.
