The endorsement comes at a time of growing uncertainty on the world stage, with Russia continuing its war against Ukraine and launching one of its largest attacks on Kyiv last night, using waves of drones and missiles.
Against that backdrop, defence, national security and military readiness have moved sharply up the political agenda, both nationally and locally.
Speaking after Armed Forces Day celebrations in Swindon, Stone said Carns would currently be his preferred candidate should Labour ever face a leadership contest. Will Stone said:
“If there were to be a leadership contest, I would assess the candidates and what they are pledging first. But at this point Al Carns is the person I would most likely support, he has an exceptional record of public service, ex special forces, strong leadership credentials and understands duty and country in a way that resonates with people across the UK. I think he has the qualities to be a future Prime Minister.”

The comments are notable given the military backgrounds of both men. Before entering Parliament, Stone served with the 1st Battalion The Rifles after enlisting in 2013. During his Army career he served as a Mortarman and Physical Training Instructor, completed demanding operational and overseas deployments, including exercises in Cyprus, and represented the Army in Brazilian Jiu-Jitsu and Judo competitions at both European and World Championship level.
His commanding officer described his conduct as “exemplary”, praising his professionalism, leadership and ability to set an example to junior soldiers.
Carns’ military record is even more distinguished, as the former Royal Marines officer completed multiple operational tours, including Afghanistan, and became one of the most highly decorated servicemen of his generation. He was awarded the Military Cross for gallantry, later received the Distinguished Service Order and OBE, before entering Parliament and serving as Armed Forces Minister.
Carns recently left Government amid growing debate over Britain’s defence priorities, a move which prompted fresh speculation about his future political ambitions and whether he could one day emerge as a contender for Labour’s top job.

For Swindon, the discussion carries particular significance. The town’s links to Britain’s defence sector continue to grow. The Ministry of Defence recently established a major new presence in Swindon through its UK Strategic Command operations, while defence and advanced engineering companies have increasingly chosen the town as a base for investment and expansion.
Armed Forces Day itself attracted hundreds of veterans, serving personnel, cadets and families to Linear Park, celebrating the contribution made by the Armed Forces both locally and nationally.
Reflecting on the event, Stone said:
“I think it’s a really important day to remember the veterans, the families and the existing service personnel.”
While there is currently no Labour leadership contest underway, Stone’s remarks provide a clear indication of where his support would lie if one were to take place.
At a time when war in Europe has once again brought defence and national security into sharp focus, the Swindon MP’s backing of Carns suggests he believes future political leaders should bring more than political experience to the role.
In his view, they should also understand service, sacrifice and the realities of protecting the country.
And if Labour members are ever asked to choose a new leader, Stone has made clear who he would most likely be backing.
