Arctic and High North

The reality is that this is not about politics. This is about sincerity around our national security decisions. An independent Scotland would weaken not just the security of the UK—of Scotland, England, Wales and Northern Ireland—but the whole European security architecture and NATO as a whole. At this point in time, a worse decision could not possibly even be fathomed.

Some comments were made earlier about whether we have a frontline with Russia. The reality is that we do. As my hon. Friend the Member for Dunfermline and Dollar mentioned, it sits in the north Atlantic. When it comes to being scared of Russia, last time I checked the military dictionary, that word definitely did not exist. If someone from industry sees a Russian frigate or submarine near the CNI, I can guarantee that there will be a Royal Navy, NATO or European submarine or frigate very close by.

Although much of the current attention is focused on Ukraine, being ready to fight means being alert to every danger. We must continue working ever more closely with our allies to address emerging threats wherever they may arise. Today’s debate is a welcome opportunity to discuss a part of the world that is becoming increasingly contested by the major powers.

Having been largely inaccessible to navies in the past, the High North and Arctic are changing at an unprecedented and accelerating rate. Global warming is transforming the Arctic from frozen expanses to a 21st-century geopolitical hotspot. As melting ice opens up new sea routes, the established security balance across the top of the world will be fundamentally reshaped forever. Routes between the Atlantic and Pacific will become increasingly navigable for more of the year, bringing the continents of Asia, Europe and North America closer than ever before.

Competition to exploit the region’s valuable natural resources is growing, too. China is extending its activity in the Arctic, having recently sent more icebreakers and research vessels to probe its expanses and declaring itself a near-Arctic state. We are under no illusion about how the changing Arctic environment poses new challenges, both commercially and militarily.

Russia remains the most acute danger to the security of the northern near Atlantic, and its operations within a more navigable Arctic are an increasing part of that threat. It is sobering to realise that Vladimir Putin controls more than half of the entire Arctic’s coastline. The increased militarisation of Russia’s Arctic territory, including investment in bases and air and coastal defence capabilities, is of increasing concern. For example, Russia has established a new northern joint strategic command, reopening cold war-era bases above the Arctic circle, including a fully operational base on Franz Josef island and another on Kotelny island.

In the north Atlantic, Russian submarine activity is nearing the highest levels since the cold war. Changes in the region directly impact us and our security here in the UK, as one of the Arctic’s nearest neighbours—whether it is from increasing threats or damage to subsea electricity or telecommunication cables in the Baltic sea or from the increase in Russian activity in the key Greenland-Iceland-UK gap involving surface and sub-surface vessels and aircraft.

As climate change opens new routes and access to resources, and as we are one of the Arctic’s closest neighbours, how are the Government working with allies to strengthen our collective security in the region in the face of climate change to ensure that the UK is able to protect our long-term interests alongside other partners from non-Arctic states?

[Al Carns]

As my hon. Friend will know, we have various multilateral treaties, including working with the JEF and NATO to ensure that any implications from global warming are carefully considered and that security recommendations are put in place to deal with them should they arise.

NATO has made it clear that defence of the High North is a key strategic imperative. The addition of Sweden and Finland to the alliance has significantly strengthened NATO’s hand in the region. Indeed, Nordic countries have spent decades managing Moscow’s interests in the High North, and they bring valuable experience to help counter the threat that Putin’s forces present today. As part of the UK-led joint expeditionary force, we are working alongside them to enhance collective security across Northern Europe.

We have assets across all three main services and interoperability with our allies that can project force deep into the High North. For example, a recent agreement between Britain and Norway will see our commando forces, led by the Royal Marines, operating in Norway all year round to defend NATO’s northern flank. They will take part in Exercise Cold Response, the largest military exercise in Norway this year, with a 40% increase in Royal Marine activity. I know the exercise well: in 2022, I took part in it as the chief of staff of the UK strike force, operating a multinational fleet, dozens of ships, aircraft and thousands of forces across the Arctic. I spent time during my 24 years—many of it unhappy, in a snowhole—in the Arctic as part of the Royal Marines, as a mountain leader.

We train hard for those operations in the Arctic. We have some of the best troops in the world, and we work exceptionally hard with Norway and Sweden and with Finnish forces. What is more, we have established the littoral maritime response force, with dedicated personnel, ships and helicopters operating in the High North. We have bought new generation anti-submarine frigates, have just completed a huge deal with the Norwegians to ensure interoperability across the Type 26 fleet, and have launched the groundbreaking Atlantic Bastion programme to protect the UK from Russian undersea threats. It is all part of widespread and regular operations involving our armed forces to maintain operational readiness across northern Europe.

The MOD keeps Russia’s military posture in the region under continuous review and conducts wider strategic monitoring with our allies. Of course, we recognise that Russia is an Arctic state with a legitimate presence, but we have to be clear that we will protect, and if necessary assert, our rights to safeguard security and international law. That includes honouring the integrity—
