Retired US general David Petraeus has indicated that he would serve in President-elect Donald Trump's administration if he was offered a job, according to an interview on BBC radio.
The Wall Street Journal has reported that General Petraeus, who resigned as CIA chief in 2012 after an extra-marital affair was revealed, was under consideration for the post of defence secretary.
Asked if he would agree to serve in the Trump administration, he said: "I've been in a position before where a president has turned to me in the Oval Office in a difficult moment and .... said 'I'm asking you as your president and commander-in-chief to take command of the International Security Assistance Force in Afghanistan'.
"The only response can be 'yes, Mr President'."
General Petraeus was a four-star general in the US Army and oversaw international forces in both Iraq and Afghanistan. He was later appointed as CIA director by President Barack Obama.
Asked during his BBC interview if he thought Mr Trump had the right temperament to be president, General Petraeus said: "We're going to have to see.
"I'm not someone who's had contact with him in the past. I don't know how he operates. It's interesting that those who have been talking to him have said he's a very personable, very hospitable, very gracious guy, full of questions and dialogue.
"This is a guy who's done pretty well in life."
Pressed further on the pressures of the office of US president and whether he had confidence that Mr Trump was capable of doing the job, General Petraeus said: "I think so, yes. It's up to Americans not only to hope that that is the case, but if they can, endeavour to help him."
Trump taps Nikki Haley as US ambassador to UN
Mr Trump ihas selected South Carolina Governor Nikki Haley to be his ambassador to the United Nations.
Mr Trump's transition team confirmed the choice in a statement saying "Governor Haley has a proven track record of bringing people together regardless of background or party affiliation."
The Republican rising star, the daughter of Indian immigrants is the first woman Mr Trump has nominated to his cabinet.
The 44-year-old has little foreign policy experience but injects diversity into Mr Trump's team after a divisive election in which the real estate billionaire was outspoken in his criticism of immigration and faced accusations of sexual harassment from a series of women.
Ms Haley was fiercely critical of Mr Trump during his campaign, calling him "everything a governor doesn't want in a president" in February.
She supported Senator Marco Rubio during the Republican primary race before endorsing Senator Ted Cruz.
Her nomination must be confirmed by the Senate.
