This comes as former armed forces minister James Heappey said that the UK must prepare for war despite being "a long way behind."
Heapy is not the only MP concerned about the prospect of war, Deputy Prime Minister, Oliver Dowden, has warned threats to the UK’s national security are increasing and the "risk landscape" is the worst since the Cold War.
Dowden told GB News: "Over the past few months and years we have seen the risk landscape affecting the United Kingdom increasing considerably.

Earlier in the conversation, Robert Fox spoke about how the war could look different this time around and we are at risk of cyber attacks.
He explained: "We're not going to go back to preparing for war as we did before like we did in 1939 or 1940. It's about resilience.
"It's the whole piece that we're under threat constantly from cyber, from space.
"By that I mean satellite communication. We want light, flexible, contemporary forces.
"The British are going to work with forces like the French and other nothern countries
"It's all about how we face these very strange threats which we're very focused on.
"It's gonna be a mixture of hybrids and the world is very, very unstable at the moment."
