I don't really understand the fashion for countries to break away from the larger group but Catalonia has been threatening to break away from Spain for some time now and things are balanced rather precariously as the Madrid Government plan to invoke Article 155 which removes the regions autonomy and enforce direct rule including taking control of the Catalonian police force and media.
The speaker of the Catalan Parliament has called it 'an authoritarian coup' and after Barcelona Mayor Ada Colau called for demonstrations, tens of thousands turned out in a protest.
Spanish law dictates that elections must be held within six months of Article 155 being triggered, but Prime Minister Mr Rajoy said it was imperative that the vote be held much sooner.
Three weeks ago, of the 43% of Catalans who took part, 90% voted in favour of independence although many anti-independence supporters boycotted the ballot, arguing it was not valid.
The Catalonian leaders then signed a declaration of independence, but immediately suspended it in order to allow for talks.
The concern is that after the violence and heavy handed approach from Spanish police during the recent vote, if the Spanish Government does enforce direct rule, the smouldering tinderbox will explode spectacularly and as many other nations are trying to thwart break up's in their own nations, Catalonian wishes will be violently and brutally suppressed as the EU and EU nations look the other way.
