Scotland’s first minister, Nicola Sturgeon, has condemned the detail in the leaked political declaration on fishing rights as “yet another Tory sell-out of Scotland’s fishermen”. Asked about the declaration during first minister’s questions at the Holyrood parliament on Thursday lunchtime, she referred to the paragraph that states “within the context of the overall economic partnership the parties should cooperate on inter alia access to waters and quota shares” and contrasted this with the letter written to Theresa May last week by her 13 Scottish Conservative MPs which warned: “Access and quota shares cannot be included in the future economic partnership, allowing the UK to become an independent coastal state both in principle and in practice.”

Sturgeon said that if Scottish secretary David Mundell (one of the 13) was still in office by the end of today he would have forfeited for ever any scrap of credibility or principle he had.

While FMQs continued, Mundell himself tweeted that he would “not take lessons on standing up for fisherman from Nicola Sturgeon who is committed to trapping them in the hated common fisheries policy”.

David Mundell (@DavidMundellDCT) The surest way to guarantee the EU access to Scottish waters would be to rejoin the CFP - exactly what @NicolaSturgeon is demanding

But there no doubt that fishing rights continue to be a flashpoint for May’s Scottish colleagues. Scottish Tory MP Andrew Bowie welcomed the deal as “getting us out of the CFP”, while another of the 13, the hardline Brexiteer Ross Thomson, described it as “unacceptable”, stating: “This means sovereignty over our waters sacrificed for a trade deal. That is unacceptable. We must be a normal independent coastal state like Norway.”
