Great Britain can lose parts of its territory, dangerous scenario for London

In the event that Great Britain leaves the European Union without concluding an agreement with Brussels on the format of further relations, Argentina will raise the issue of the territorial affiliation of the Falkland Islands.
First of all, Buenos Aires will make efforts to strengthen ties with the inhabitants of the archipelago. In Argentina, hoping that brexit without a deal will make the dialogue with the islanders "truly productive." This was in an interview with The Daily Telegraph told the Minister of Foreign Affairs of Argentina, Jorge Fori.
The diplomat suggested that Argentina could take advantage of the weakening of diplomatic ties between Britain and the EU to increase pressure on the issue of establishing his country’s control over the Falkland Islands.
“If we assume that the EU member states will not support Britain’s claims to the Malvinas Islands (the Argentine name is Falklands. - RT), we are ready ... to engage in dialogue in order to work out the most suitable solution for the islanders, which will significantly strengthen their ties with Argentina “- Fori quotes the Daily Telegraph.
Argentine authorities intend to "build up" diplomatic efforts to transfer the archipelago under its jurisdiction, and Brexit is the most convenient reason for this. The fact is that after the withdrawal of Britain from the EU, all treaties that previously operated in the United Kingdom - EU are automatically canceled.
For example, for London, the Lisbon Treaty of 2009 will cease to operate, according to which the EU member states consider the Falkland Islands as a British overseas territory covered by European legal norms.

It should be noted that the Falkland Islands is not the only region whose problems were actualized against the background of Brexit.
Northern Ireland presented its ultimatum to London: the region does not agree to sever ties with the Republic of Ireland and create a hard border on the Emerald Isle. A similar position is taken by Dublin, which threatened to block the deal between London and the EU in the event that the agreement does not provide for special conditions for Northern Ireland. In London, for their part, they are not ready to embark on a customs border on the Irish Sea - in fact, this would be the first step towards the separation of Northern Ireland from the kingdom.
