RUTH Davidson and Michael Gove have been urged to apologise after it emerged the UK will be subject to the EU's Common Fisheries Policy after March next year - despite promising just over a week ago it wouldn't.

The call came from Fergus Ewing, the Scottish Government's rural economy secretary, after a deal on the terms of the Brexit transition, released today, stated clearly the UK agreed to abide by CFP rules during the transition period, which ends at the end of 2020.

"The Tories have sold out the Scottish fishing industry once again and Ruth Davidson should be shame-faced for her fastest broken Brexit promise yet. Just last week she said “Britain will leave the CFP as of March 2019”," said Ewing.

"Now we know not only will the UK have to abide by CFP rules during the transition period, it will lose the voting rights it has now. The Tories have delivered the worst possible outcome for Scotland’s fishing industry."

He added: "It is outrageous that Ruth Davidson and Michael Gove could have issued such a misleading statement last weekend when they must have known what was about to happen – and they must both now apologise for their broken promise. The Tories have demonstrated once again that for them Scottish interests are expendable.They are so arrogant they now think they can do whatever they want to Scotland and get away with it."

Access to UK's fishing territory was a key issue during the EU referendum with many fishing communities backing a leave vote after being told Brexit would mean 'taking back control' of UK waters.

Today the Scottish Fishermen's Federation (SFF) reacted angrily to the deal, though appeared to hold out hope that after the transition period they would still be able to achieve their ambition to withdraw from the CFP.

"This falls far short of an acceptable deal. We will leave the EU and leave the CFP, but hand back sovereignty over our seas a few seconds later. Our fishing communities’ fortunes will still be subject to the whim and largesse of the EU for another two years," said Bertie Armstrong, chief executive.

Armstrong went on to suggest his industry could harden its stance further in any future negotiations with the EU. He also demanded a written guarantee from the UK Government that after the transition period, Britain would not allow any EU country access to its waters unless negotiated on a year to year basis.

"We do not trust them [the EU] to look after us. So we issue this warning to the EU - be careful what you do or the consequences later will be severe. To our politicians we say this: some have tried to secure a better deal but our governments have let us down." he said.

"As a consequence, we expect a written, cast iron guarantee that after the implementation period, sovereignty will mean sovereignty and we will not enter into any deal which gives any other nation or the EU continued rights of access or quota other than those negotiated as part of the annual Coastal States negotiations.”

Davidson did not apologise and described the terms of the transition period as 'an undoubted disappointment', blaming the EU for 'not willing to' shift on fishing access.

"During these negotiations, we wanted to gain control over our waters from as early as the end of next year," she said.

"The EU was not willing to move on this. That we now have to wait until 2020 to assume full control is an undoubted disappointment. Having spoken to fishing leaders today, I know they are deeply frustrated with this outcome. There is no ignoring the fact that this falls short of what they had hoped for in the short-term."

She added: "I’ve made clear to them that I will continue to do everything in my power to ensure their interests are protected during the implementation period and beyond. Any attempt by the EU to use the implementation period to weaken their hand would be a breach of the agreement. Over the long-term, today's agreement makes clear that, from 2020, the UK will be an independent coastal state, deciding who can access our waters and on what terms.I am more determined than ever to ensure that this long-term prize for our fishing industry is seized."

Davidson went on to say that over the longer term she would not support a deal that did not see "full control over fish stocks and vessel access."

Both the UK and the EU now hope the terms of an agreement on the transitional period can be signed off by the Prime Minister and other leaders at the EU summit this week.

The UK's Brexit negotiator David Davis said he hoped negotiations on the UK's future relationship with the EU - including a free trade agreement - could now start "as soon as is possible".

He said: "We need to get on with this now. We need to come to agreement on this as fast as we can.

"That is in the interests of businesses within the European Union and businesses within the United Kingdom.

"This will be the biggest, most comprehensive, most effective trade deal ever."
