>> The Chilcot Report casting fresh light on just how close London and Washington once were. The two moving in lock step during the march to war in Iraq. But recent events also have people asking whether the so called special relationship can survive Brexit. Reuters' UK correspondent William James says the close ties have proved surprisingly durable.
>> I think although the Iraq war, the scene is there, it's a very negative thing in British foreign policy and there's lots of criticism of the decision to go in with the US. Actually, not that much has changed. Brittain and the US have this special relationship. They remain extremely close allies.
We saw that in the e-referendum campaign when President Obama came over here and tried to back up David Cameron's argument that leaving the European Union would be a mistake.>> Some think Obama's intervention actually cost votes for the Remain camp, but the special relationship remains strong in many areas.
British spies, for example, get privileged access to US intelligence. Now many are wondering if such ties are in danger.>> If anything, Brexit has heightened the need for Britain to have that special relationship with the US, so I don't think things will change massively. In fact, we may even become more aligned with them because what Britain has essentially done is cut itself off from its European allies, the closest geographical allies, closest geographical trading partners.
And instead, in place of that relationship is now looking across the Atlantic to the US.>> But the transatlantic relationship still faces dangers. As Henry Kissinger has once supposed to have asked, who do I call if I want to speak to Europe? After Brexit, it might not be the British Prime Minister.
