In the UK parliament, Penny Mordaunt questioned “how many SNP figures” will end up “in the dock” as she slapped down down another dubious attack from her opposite number Deidre Brock, reports the Scottish Daily Express.

The Edinburgh North and Leith MP clearly annoyed the Leader of the House by suggesting she was “surprised” she had not been at an “extreme far-right” conference organised by a US think tank.

Ms Mordaunt decided to torpedo her in response. She said the “SNP is hiking taxes, spending like there is no tomorrow and failing to deliver on decent public services”, before referencing Lorna Slater’s charter boat trip to Rum due to CalMac ferry shortages.

She added: “I wonder whether the honourable Lady and her colleagues have read any of Audit Scotland’s reports or acted on any of its recommendations. They have no concept of the catalogue we now have of arrests and raids and multiple police investigations into the mismanagement of their party finances, and of how negatively that has reflected on Scottish politics.

“We also have the poor stewardship of public funds and an increasing question about the ongoing saga of the Scottish National Investment Bank. We are wondering not just how much longer those CalMac ferries will be in the dock, but how many SNP figures will be as well.”

She said the Conservative Friends of the Ocean group supported the creation of HPMAs, adding: “I know that the Conservatives are desperate to win back the Scottish coastal communities after their Brexit catastrophe, but those communities will see through this hypocrisy.

And she claimed her “jaw nearly hit the floor” when she realised Ms Mordaunt herself was patron of the group, adding: “Will she be resigning from Government to honour her role as patron, or resigning as patron to uphold Government policy?”

Ms Mordaunt said: “I am very proud of my Government’s record, both on improving our water quality and boosting the economic resilience of coastal communities…the concerns that have been raised by many coastal communities is because the Scottish Government does not consult and it does not listen to those communities.
