Apparently I was being prophetic when joking about 'sacrifice Gibraltar for a better trade deal' last week.
Spain has made it known that they wish to involve the status of Gibraltar in the Brexit negotiations.
In response, former conservative party leader Michael Howard has said that 'Our PM May is willing and able to defend Gibraltar, like Margareth Thatcher defended the Falkland islands', implying the UK would be willing to enter an armed conflict with the EU over Gibraltar if nescessary.
Furthermore, the Spanish minister of foreign affairs announced that SPain will not object to Scottish EU membership. This comes as a surprise, since Spain itself has issues with parts of the country wanting independence, and has thusfar been against Scottish independence.
The concept plan of Donald Tusk includes the Spanish wish of having a say over Gibraltar: In 1713, the Peace of Utrecht formally added Gibraltar to the British Empire. Donald Tusk's concept plan includes renegotiation of the Treaty of Utrecht. The plans will allow Spain to exclude the conflicted area of Gibraltar from a EU - UK trade agreement, if the UK refuses to sign a bilateral agreement over Gibraltar with Spain.
The government in Madrid already announced that Gibraltar airport can by no means fall under a EU - UK trade agreement.
Unsurprisingly, 96% of the inhabitants of Gibraltar voted against the Brexit.
