The Conservative MP for Banff and Buchan called the decision “morally wrong” and called for a change in Faroese policy on the issue.

Mr Duguid will ask Faroese Prime Minister Bárður á Steig Nielsen why he is “turning a blind eye” to Putin’s barbaric regime when he meets him later this week.

The area shared between the UK and the Faroe Islands was primarily intended for oil and gas exploration, but it also includes a fisheries agreement whereby each state can issue fishing licenses to third parties who work in territorial waters the other.

But the UK and EU pelagic industries raised concerns when the Faroes unilaterally increased their blue whiting quota from 82,000 tonnes to 267,413 tonnes. It is not yet known how much of the 267,413 tonnes of the Faroese quota has been allocated to Russia and its fishing industry.

The MP said: “It is morally wrong that the Faroe Islands continue to allow Russian vessels access to this area – given the sanctions imposed on Putin’s regime by the UK and its allies.

“That is why I will ask the Prime Minister of the Faroe Islands how he can justify maintaining such ties with Russia.

“No country should be fueling Putin’s barbaric war regime, which is why the British government will not allow any Russian-flagged vessel to fish in British waters and the Faroe Islands should do the same.

“I will also ask for an explanation as to why the Faroe Islands and Norway have unilaterally increased their own blue whiting quota beyond established scientific advice.

“I hope my meeting with Bárður in Steig Nielsen will make him think twice before allowing this to continue.”

The Faroes consist of 18 islands, inhabited by 52,000 people. The archipelago lies in the middle of the North Atlantic, at the center of the so-called GIUK gap, a transit route between Greenland, Iceland and the north of the United Kingdom, which has regained the strategic importance of which she enjoyed during the cold war.
