The British public are unlikely to back involvement in Donal

Director of the British Foreign Policy Group, Sophia Gaston, wrote for the New Statesman as tensions escalated between the United States and Iran - citing new BFPG research to argue that Boris Johnson may be constrained by public opinion if he chooses to involve British forces in Donald Trump's conflict with Iran.

She wrote: "there have been many turning points in British foreign policy, but in terms of its implications for British governance, and the fusing of the domestic and international spheres, the long-term influence of the war in Iraq cannot be overstated. Analysis of public opinion towards military interventionism makes clear that it precipitated a dramatic decline in support for proactive defence activities."
