Iran must never develop a nuclear weapon. We will use all diplomatic levers at our disposal to support a negotiated outcome and ensure Iran does not develop a nuclear weapon including through the UN snapback mechanism, if necessary.

The ceasefire provides a diplomatic window for US/Iran talks to resume. Through numerous bilateral conversations with counterparts since 13 June, the UK is urging Iran to engage urgently and directly in negotiation and working with the US to support this.
