The Swing becomes clearer when we the swing in the Basque TErritories.
The 2009 election saw the EAJ-PNV lose power to the Federal PSE and for some commentators to question whether the Independence movement has lost its momentum .
However the major facyor was the exclusion of Patries with links to ETA and the new group Aralar only managed to pick up a few seats as some voters boycotted the election.
Since 38 seats are needed for an overall majority may have to seek support from the Federal parties if it is reluctant to pres for further Independence . But the Euskal Herria Bildu (Basque Country Gather (EHB) which contain Parties who are members along with Plaid in the European Free alliance means that the EAJ-PNVan.t ignore the message from the Basque electorate .
Indeed the 3 years that they were out of power could have shaken EAJ-PNV out of their complacency and they could well like Catalonia seek to hold a referendum .
A few years ago commentators were trying to give the impression that the National Movements had lost their Momentum but it looks very different now and with Catalalan having a new impetus again also coming from the left and with Nieuw-Vlaamse Alliancie (N-VA) (admittedly more conservative ) scoring major victories in municipal elections last week in Belgium. We may see an increase for autonomy partial ot full throughout Europe.
At present Wales is far behind. but who knows what the effect of this New-Nationalism will have on us?
