Foreign Secretary William Hague has said plans to re-open the British Embassy in Tehran are an "important step forward" in relations with Iran.

Mr Hague said the "circumstances were right" following an improvement in bilateral relations in recent months.

Full diplomatic relations with Iran were suspended after attacks on the British embassy in Iran in 2011.
