Britain's armed forces are stepping up their contingency planning for potential military action against Iran amid mounting concern about Tehran's nuclear enrichment programme, the Guardian has learned.
The Ministry of Defence believes the US may decide to fast-forward plans for targeted missile strikes at some key Iranian facilities. British officials say that if Washington presses ahead it will seek, and receive, UK military help for any mission, despite some deep reservations within the coalition government.
