In L'Aquila, Italy on Thursday, Prime Minister Stephen Harper was late to arrive at a G8 summit photo shoot, leaving his world leader colleagues standing around while they waited for him to show up.

Other dignitaries started calling out the prime minister's name, when it was apparent that Harper was not at the Thursday shoot.

Harper was then seen rushing to the shoot with his entourage, arriving about two minutes after U.S. President Barack Obama had jogged in late to the same shoot.

When the prime minister arrived, he got cheers from the dignitaries who had been waiting for him for about a minute and 40 seconds.

In the end, Harper was able to make the shoot, unlike Egyptian President Hosni Mubarak, who pulled up on a golf cart after the photo op was over.

Harper's spokesperson, Dimitri Soudas, declined to give details on why the prime minister arrived late to the photo shoot.

"I don't think you're paying attention to the summit ... The prime minister was at the photo op," Soudas said Thursday.

Harper's gaffe follows another photo foul-up that took place in April, at the G20 meeting in London. Continued....
