LONDON, July 15

Britain hopes to re-open its embassy in Iran before the end of the year, foreign minister Philip Hammond said on Wednesday following an agreement between Iran and six major world powers over Tehran’s nuclear programme.

After more than a decade of negotiations, Iran agreed yesterday to long-term curbs on a nuclear programme that the West suspected was aimed at creating an atomic bomb. In return, the United States, European Union and United Nations will lift sanctions and unfreeze billions of dollars of Iranian assets.

“I very much hope that we will be in a position to re-open our respective embassies before the end of the year,” Hammond said in parliament.

The re-opening was dependent on resolving some technical issues, he added, without elaborating.

Diplomatic relations were suspended and the British embassy was closed after hundreds of Iranian demonstrators stormed the building in November 2011.

Hammond also said he had spoken to British finance minister George Osborne to ensure that the country was ready to capitalise on the “quite substantial” business opportunities that would arise from the diplomatic agreement.

“I think Iran will want to use some of the unfrozen assets to address some really very large infrastructure deficits, including in the oil and gas production industry, where the United Kingdom  is very well placed to play a role,” Hammond said.
