A former special forces colonel, government minister Al Carns was this week on manouevres cautioning that the UK must ready itself for war with Russia.

“The threat of conflict is at Europe’s door once more. That’s the reality. We’ve got to be prepared to deter it,” he stated, in remarks that exceed previous warnings by his boss, the defence secretary.

“Collectively, everybody – what is their role if we get caught in an fight for survival, and what do they need to be aware they need to do and what they can’t do, and how do we rally the nation to support a military endeavour?”

It was blunt language from the middle-aged Scottish-born MP, who has had an exceptionally swift rise to his role of minister for the military.

Rapid Rise to Prominence

Naturally for a politician with a background in the armed forces, there is conjecture about whether he is future leadership material – as with, at various points, previous colleagues from a service background before him.

This time, however, some ruling party MPs think there could be a genuine possibility of Carns being a candidate if and when the opportunity arises.

One of the reasons for that is that Carns has been involved in politics for longer than it seems, as a former military adviser to multiple previous defence secretaries.

But there is also the danger of being over-promoted as a politician with a personal history colleagues think will resonate with the public – without enough thought of whether they have the experience and shrewdness to make it to the top.

From the Battlefield to Westminster

Carns was born in Aberdeen, and state educated, before enlisting in the Royal Marines in 1999 at the age of 19. He advanced his career and was awarded the Military Cross in 2011 “in recognition of gallant and distinguished services in Afghanistan”.

It came as a shock when he resigned from the armed forces after 24 years of service to stand as an MP in Birmingham Selly Oak, shortly before he was due to be promoted to brigadier.

And in a sign he was immediately identified as a talent, the prime minister appointed him as a junior veterans minister straight after the 2024 election. He was elevated later that year to the more prominent position with a portfolio covering all the military.

Media Presence and Political Attacks

Chiselled and confident, Carns has been an periodic spokesperson for the government, and has been an effective political attack dog when putting pressure on rival parties over issues of national security.

He has also found time to set a new global benchmark this year along with former military colleagues by climbing Mount Everest in under five days without acclimatising on the mountain, aided by xenon gas.

Leadership Speculation and Internal Caution

His name entered the conversation as a possible future leader in earnest around the time of a deputy contest last autumn, when his supporters began canvassing colleagues about a run for the job. That did not gain traction, with the prime minister's office strongly supporting another candidate.

Since then, profiles of Carns have begun to appear in the media, with one newspaper presenting him as the “Action Man” that some were trying to stop from challenging the prime minister.

While some MPs think he could be leadership material, others think he is making himself appear overly eager when there is no opening at the top. There is also a apprehension about the rapid rise of a high flyer from outside politics.

“It's not proven that being senior in the military equates to being any good at politics any more than being a top prosecutor,” says one MP. “He is an unknown quantity.”
