Britain’s national security adviser, Jonathan Powell, attended the final talks between the US and Iran and judged that the offer made by Tehran on its nuclear programme was significant enough to prevent a rush to war, the Guardian can reveal.
Powell thought progress had been made in Geneva in late February and that the deal proposed by Iran was “surprising”, according to sources.
Powell’s attendance at the Geneva talks, as well as at a previous set of meetings earlier in the month in the Swiss city, helps in part to explain the UK government’s reluctance to back the US attack on Iran, a reluctance that has put the UK-US relationship under unprecedented strain.
The UK saw no compelling evidence of an imminent threat of an Iranian missile attack on Europe, or of Iran securing a nuclear weapon. This is the first time it has become clear that Britain was so closely involved in the talks, and so had good reason to decide whether diplomatic options had been exhausted and a US attack was necessary.
Instead the UK regarded the attack as unlawful and premature since Powell believed the path remained open to a negotiated solution to the long-running issue of how Iran could reassure the US that it was not seeking a nuclear weapon.
