The state of the British Armed Forces is becoming increasingly “worrying”, senior military sources have warned.

Numerous senior Army and Navy sources have expressed concern to The Telegraph over the Government’s refusal to commit to an exact timeline of raising defence spending to 2.5 per cent of GDP, with many saying the figure is not enough in the first place.

On Friday, The Telegraph revealed that military chiefs had warned Sir Keir Starmer that the current suggested figure of defence spending “won’t touch the sides”.

The fear within the military is that it will have to lessen its ambitions if it cannot secure more funding. 

It comes at a critical time when Donald Trump has called on Nato member states to spend 5 per cent on defence in a bid to make European nations take on more responsibility for Ukraine as well as their own security.
