NICOLA Sturgeon has sent a message to Yes activists, including an appeal to put a sign on protecting Scotland's democracy up on their windows.

The First Minister said the United Kingdom is no longer a partnership of equals as she urged the Yes movement to mobilise.

She encouraged Yessers to put sigs up in their windows.

Sturgeon said: "Earlier today, the Supreme Court delivered its judgment on the Lord Advocate’s reference, seeking clarity on whether or not the Scotland Act 1998 allows the Scottish Parliament to legislate for a referendum on independence.

"The Court was not asked to decide if there is a democratic mandate for a referendum.

"The mandate and parliamentary majority for a referendum is undeniable.

"Nor was the Court asked if Scotland should be independent. Only the Scottish people can be the judge of that.

"What today’s ruling tells us, however, is that the Scotland Act does not in fact uphold that long held understanding of the basis of the relationships that constitute the UK - on the contrary, it shatters that understanding completely.

"A so-called partnership in which one partner is denied the right to choose a different future - or even to ask itself the question — cannot be described in any way as voluntary or even a partnership at all. 

"It is Westminster that is blocking the democratic will of the people of Scotland.  

"The immediate question, of course, is what happens now.

"I will be asking our National Executive Committee to convene a special party conference in the new year to discuss and agree the detail of a proposed de facto referendum.

"Watch the people of Edinburgh respond to today's judgement on Facebook and Twitter.

"In the meantime, the SNP will launch and mobilise a major campaign in defence of Scottish democracy.

"Initially, you can show your support by displaying this sign in your window.

"Fundamentally, our job today is the same as it was yesterday.

"It is to persuade a majority of the Scottish people of the fact that independence is the best future for Scotland - and ensure a democratic process that allows majority support to be established beyond doubt.

"We have work to do. Let us inspire with hope in our hearts.

"With optimism, confidence and determination - let’s get on and finish the job. Together, let’s secure independence for Scotland.
