***UPDATE*** Defense Department spokesman Geoff Morrell released this statement: 
  
 Despite some sensational speculation by one of the London papers, I can assure you General Petraeus is not quitting as ISAF commander, but nor does he plan to stay in Afghanistan forever. Obviously he will rotate out at some point, but that point has not yet been determined and it will not occur anytime soon. Until then, he will continue to ably lead our coalition forces in Afghanistan. 
  
 General David Petraeus is expected to leave his post as commander of United States troops in Afghanistan, the Times Of London reports early Tuesday evening. 
  
 The Washington Post reported earlier in the day: 
  
 No final decisions have been made, but military officials said that Petraeus, who took command last July, will rotate out of Afghanistan before the end of the year. The general who replaces Petraeus will have to navigate a tricky relationship with Afghan President Hamid Karzai and Pakistani leaders... 
  
 According to the Times, the Pentagon is expected to name a replacement for Petraeus by the end of the year. 
  
 President Barack Obama tapped Petraeus to replace Gen. Stanley McChrystal last summer after controversy swirling around critical comments the then-commander made about Obama administration officials to Rolling Stone landed him out of his post. 
  
 Reuters reports: 
  
 Petraeus has been talked about for a while as a possible successor to Admiral Mike Mullen, Chairman of the Joint Chiefs of Staff (CJCS), who is expected to retire in October. Any move would be part of a broader shake-up in the administration, which will also see Defense Secretary Robert Gates retire this year. ... His departure, especially with Gates on his way out, could create the space for Obama to recalibrate Afghan strategy, backing away from the military surge and focusing more on a political settlement - if he wants to do so. 
  
 The Post notes that Petraeus is not the only leading U.S. official in Afghanistan expected to rotate out of his post this year. Among others, U.S. ambassador to Afghanistan Karl Eikenberry, who has expressed reservations about the country's Afghan war strategy, will reportedly leave his job in coming months. 
  
 The Times reports: 
  
 It forms part of a sweeping reorganisation of top American officials in Afghanistan, which the Obama Administration hopes to present as proof that its strategy does not depend on the towering reputation of one man. ||||| The Pentagon has denied that the commander of US and Nato forces in Afghanistan, General David Petraeus, is planning to quit by the end of the year. 
  
 The Times reported that the Pentagon was looking to replace Petraeus, who was appointed eight months ago. 
  
 But the Pentagon said that while it constantly reviewed rotations, particularly as a number of senior posts were about to fall vacant, no decision had been made about Petraeus. 
  
 Petraeus is popular in the US, credited with first turning around Iraq and now, as head of Nato's International Security Assistance Force (Isaf), helping to reverse Taliban gains in southern Afghanistan and bring a degree of stability. 
  
 Geoff Morrell, the Pentagon spokesman, said: "Despite some sensational speculation by one of the London papers, I can assure you General Petraeus is not quitting as Isaf commander, but nor does he plan to stay in Afghanistan for ever. 
  
 "Obviously he will rotate out at some point, but that point has not yet been determined and it will not occur any time soon. Until then, he will continue to ably lead our coalition forces in Afghanistan." 
  
 By the end of the year, Petraeus will have done 18 months, a normal rotation for the post, and he would be in the running for a more senior post back in the US. 
  
 US forces are due to begin a drawdown in July but Petraeus will fight to keep as many as possible in Afghanistan to try to pacify the country, in a repeat of the strategy he used in Iraq. He might then ask to stay into next year. 
  
 Petraeus has been touted as a possible Republican presidential candidate to take on President Barack Obama for the White House next year, but has repeatedly denied he is planning to run. |||||
A:
The Pentagon moved quickly today to quash reports that it’s looking to replace David Petraeus by the end of the year. “Despite some sensational speculation by one of the London papers, I can assure you General Petraeus is not quitting,” a Pentagon spokesman said in a statement. “Obviously he will rotate out at some point, but that point has not yet been determined and it will not occur any time soon.” The “London paper” in question is the Times, which reported last night that the Pentagon was hunting for a successor to Petraeus. Earlier in the day the Washington Post reported that Petraeus would rotate out at the end of the year, the Huffington Post notes. Of course, by the end of the year Petraeus will have spent 18 months in Afghanistan, the normal rotation for the post, the Guardian observes.
