RATTLED British and US spook bosses have warned that their notion of an international world order is “under threat in a way we haven’t seen since the cold war.”

In a first-ever joint article, MI6 chief Sir Richard Moore and CIA director William Burns said that they saw the war in Ukraine coming “and were able to warn the international community,” partly by declassifying secrets to help Kiev.

The security service chiefs said there was work being done to “disrupt the reckless campaign of sabotage” across Europe by Russia, push for de-escalation in Gaza, and counterterrorism to thwart the resurgent of Isis.
