JERUSALEM (AP) — Former British Prime Minister Tony Blair on Wednesday stepped down from his post as the international community's Mideast envoy, officials said, ending a term that began with great promise but which struggled to deliver dramatic changes in its quest to promote peace between Israel and the Palestinians. The officials spoke on condition of anonymity pending a formal announcement, which was expected later Wednesday at a meeting of Quartet officials in Brussels. According to his office's website, Blair's office succeeded in helping remove dozens of Israeli checkpoints in the West Bank, easing the movement of workers and Palestinian products to markets.
