What assessment he has made of the adequacy of the UK’s defensive capacity in the North sea.

Protecting the United Kingdom and responding to threats in our territorial waters is core business. In conjunction with our allies and partners, we constantly monitor activity in UK waters and deter threats. Our warships patrol the North sea frequently to achieve that deterrence.

I thank the Minister for his answer. In the north Atlantic, Russian submarine activity has approached the most significant level since the cold war. Operations such as Dynamic Mongoose are a welcome commitment to both NATO and North sea security. How much of the new tranche of defence spending will be directed at the North sea and Arctic security?

Of course, we do not comment on our magnificent continuous at-sea deterrence. What I can say is that it is a matter of public record that we are committed to a magnificent new generation of Type 26 anti-submarine warfare frigates, which will achieve the competitive edge that keeps us all safe.

Does the Minister recognise that the seismic array situated at Eskdalemuir in my Constituency plays an important part in our defences not just in the North sea but elsewhere? Does he agree it is essential that its capability is not in any way diminished by excessive wind farm development in the immediate vicinity of the facility?

I agree with my right hon. Friend; he is absolutely right in his analysis. The broader point is that this is another example of why, undoubtedly, England and Scotland, through the Union, are safer and better together.
