What recent assessment he has made of the implications of Iran-Iraq relations for UK foreign policy; and if he will make a statement.

It is essential for Iraq's stability and prosperity that it develops constructive relationships with its neighbours, including Iran. We welcome Iranian efforts to build relations, but some elements in Iran continue to support illegitimate armed groups, undermining democracy and security. That is wholly unacceptable, as my right hon. Friend the Foreign Secretary and I have told the Iranian Foreign Minister on a number of occasions. British and coalition troops will continue to support the Iraqi Government in confronting such groups and their sponsors.

Despite President Ahmadinejad's official visit to Baghdad earlier this month, General Petraeus yesterday publicly accused the Iranians of being responsible for supplying the mortars and rocket shells that landed within the green zone. He also said that Iranian revolutionary guard elements were responsible for training the insurgents who fired those rockets. What action will the Government take against the Iranian authorities to prevent the Iranians from stoking the insurgency in Iraq?

As the hon. Gentleman knows, we have been worried for a long time about the supply of Iranian weapons, especially those of Hezbollah design—roadside bombs with special detonation devices that bear the hallmark of Hezbollah and seem to have come through elements of the Iranian security forces.

We have called on Tehran to turn its rhetoric about wanting a good relationship with its neighbour Iraq into a reality. We urge it now to try to do just that, to make sure that the relationship is based not on fear and terror, but on the understanding that if Iran is to have a safe and secure future, Iraq must be safe and secure as well.
