Once in a generation is apparently once every 8 yrs , until they get the vote they want.
That said its a rather pointless vote or pol or whatever it is, as it won't be validated or binding and therefore only those that want a yes are likely to vote in it. Likely result will be a yes vote. The UK government know this and therefore won't sanction it.
Hope the SNP spend their own money and not the UK taxpayers doing all the promotion etc. Fat chance.
Perhaps all of the UK should get a vote? Alternatively perhaps the UK should follow an EU government's path like the Spanish one and put Sturgeon on trial for sedition. The EU were OK with this remember.
Shame really, nationalist politicians just create division and hate. We could all do with less these days.
