KABUL (AFP) - Afghan President Hamid Karzai has floated the prospect of bringing forward presidential elections to April, senior officials said Wednesday, as he tries to head off intense wrangling over his future. The embattled leader, under increasing pressure at home and abroad, called in foreign ambassadors for talks on the dilemma this week, his office said. He separately summoned his vice-presidents, cabinet ministers, the speakers of parliament and other key figures to the presidency to try to wrap up consultations. The Independent Election Commission last month set the vote for August 20, saying earlier polls would be difficult because the threat of insurgent violence and logistical difficulties had delayed preparations. "No decision was made but various options, including holding the elections in April, were discussed," a well-placed senior government official told AFP, asking to remain anonymous. Asked about an electoral date of April 21, he said: "A number of options including that were discussed." The president was expected to announce his decision soon, possibly by Friday (tomorrow), the official said.
