US President Barack Obama broached the issue of General Stanley McChrystal with Prime Minister David Cameron, and vowed to consult Britain "closely" on Afghanistan, Cameron's office said on Wednesday.
The US and British leaders discussed Afghanistan in a telephonic conversation on Tuesday, along with other issues including this weekend's G20 summit in Canada, Cameron's spokesman said.
Obama himself raised the issue of McChrystal -- summoned to the White House on Wednesday amid speculation he might lose his job for disparaging remarks about top US officials -- with Cameron during the call, he said.
Speaking more generally about cooperation on Afghanistan, "the president said he would continue to consult closely with the prime minister," said the Downing Street spokesman.
Cameron's spokesman declined to be drawn on the specifics of McChrystal's comments, made in an interview with Rolling Stone magazine, beyond voicing backing for the NATO strategy which the US general is pursuing.
"It's a NATO strategy which we support," he said. "The issue here is the issue of comments made about the US administration, and therefore it's a matter for the US administration."
