Afghan Presidential Candidates to Sign Power Deal --- KABUL, Afghanistan — Afghanistan's two presidential candidates were set to a sign a power-sharing deal on national TV on Sunday, three months after a disputed runoff that threatened to plunge the country into turmoil and complicate the withdrawal of U.S. and foreign troops. -- Ashraf Ghani Ahmadzai and Abdullah Abdullah were to sign the national unity government deal at the presidential palace at noon local time (0730 GMT), said the spokesman for President Hamid Karzai. The deal, agreed to in talks that began late Saturday, follows weeks of negotiations on a power-sharing arrangement following accusations of fraud in the June runoff vote. -- The deal would be a victory for U.S. Secretary of State John Kerry, who first got the candidates to agree in principle to share power during a July visit to Afghanistan. Kerry returned to Kabul in August and has spent hours with the candidates in repeated phone calls in an effort to seal the deal. -- The deal will see Ghani Ahmadzai replace Hamid Karzai as president. Abdullah will hold the newly created post of chief executive, akin to a prime minister. --- He also believes he won a June runoff with Ghani Ahmadzai. But official totals — which the election commission said it would release on Sunday — show Ghani Ahmadzai with about 55 percent of the vote. -- A power-sharing deal was almost sealed about a week ago, but Abdullah then demanded that no vote totals from the runoff be released - More, REUTERS, NYTimes
