In a significant departure from Mr Bush’s long-standing refusal to talk to Tehran until it has abandoned its nuclear enrichment programme, William Burns, the Under-Secretary of State and America’s third most senior diplomat, will travel to Switzerland to attend talks between Iranian and European officials on Saturday. The move comes as the US considers establishing a diplomatic presence in Tehran for the first time since the closure of its Embassy in 1980. As The Times reported last week, US officials had discussed sending consular staff to the Swiss Embassy in Tehran, to handle visa applications.
