Leaving the European Union will cost the Scottish economy up to £11.2bn per year by 2030, the First Minister will say today.

The figure comes from economic analysis published in a paper by the Scottish Government.

The paper projects Scottish GDP to be between £1.7bn and £11.2bn lower per year by 2030 than it would have been if the country stayed in the EU.

Tax revenues are also predicted to shrink. The Scottish Government forecast a downfall in projected revenues, ranging from £1.7bn to £3.7bn.

This is the first in a series of planned papers outlining the impact of leaving the EU to be published by the Scottish government.

Sturgeon will unveil the paper at a press conference at Bute House later on Tuesday.

Speaking ahead of her speech, the First Minister said: "This paper shows, in the starkest possible terms, the potentially huge cost to Scotland of being taken out of the European Union and the single market.

"This analysis - based on a wide range of sources - demonstrates that leaving the EU, under any potential alternative arrangement, will have a profound and long-lasting impact on the public finances and the wider economic and societal wellbeing of both Scotland and the UK as a whole.

"That stark picture outlined today means that, whatever the model of relationship with the EU which is chosen by the UK Government in their negotiations before and after Article 50 is triggered, it will not be as economically beneficial as full EU membership.

"The only way to protect Scotland's economy - and the clear benefits which come from being part of the world's biggest single market - is to work to ensure we protect our relationship with the EU."

In the aftermath of the referendum on Britain's membership of the European Union, Sturgeon said "nothing was off the table" in her bid government's bid to keep Scotland in the EU and it was "highly likely" a second referendum on Scottish independence would be held.

Since then the First Minister has visited Brussels and Berlin for talks with European Union officials and politicians.

Sturgeon has described these talks as "useful" and has promised to continue the meetings "in the weeks and months ahead".

The paper will be unveiled on the same day the Scottish Conservative leader Ruth Davidson will urge the First Minister to get back "to the day job".

Davidson will say: ""We now need a new type of government in Scotland. One which no longer sees every issue through the prism of independence and the constitution, but one 100% committed to the job in hand.

"It's time we had a government that got back to the day job."
