Rafe Heydel-Mankoo has criticised Labour's foreign policy since taking power.
Speaking to GB News, he said: "Labor's ineptitude over the Chagos Islands, its ideological extremism and its inability, quite frankly, to see Britain's wider national security interest has opened a door for politicians like this to make to pursue claims they didn't think were possible before.
"And you're quite right, you know, from Argentina to the Caribbean, world leaders now see Labour as being weak."
