G7 leaders gather in Canada

Leaders of some of the world’s biggest economic powers arrive in the Canadian Rockies on Sunday for a Group of Seven summit, overshadowed by an escalating conflict between Israel and Iran and US President Donald Trump’s unresolved trade war with allies and rivals alike.

Israel’s strikes on Iran and Tehran’s retaliation, which appeared to catch many world leaders unawares, is the latest sign of a more volatile world as Trump seeks to withdraw the US from its role as world policeman.

Speaking on a flight to Canada to attend the summit, British Prime Minister Keir Starmer said he had discussed efforts to de-escalate the crisis with Trump and Israeli Prime Minister Benjamin Netanyahu, as well as other world leaders.

Britain is sending fighter jets and other military reinforcements to West Asia.

“We do have longstanding concerns about the nuclear programme Iran has. We do recognise Israel’s right to self-defence, but I’m absolutely clear that this needs to de-escalate,” Starmer said.

With other leaders wanting to talk to Trump in an effort to talk him out of imposing tariffs, the summit risks being a series of bilateral conversations rather than a show of unity.

Trump is the summit wild card.
