US and European allies have welcomed what they called a "significant shift" in Iran's attitude to its nuclear programme, after high-level UN talks.
Former Prime Minister and Quartet Representative to the Middle East, Tony Blair, says a 3-6 month nuclear agreement is achievable.
"If there is a serious change of policy by Iran, and a serious change of engagement over the next few months - yes it's possible to resolve this quickly."
Tony Blair joined David Eades on BBC World News.
