The hon. Gentleman is right to say that in a wide range of countries there is evidence of Iranian support for terrorist groups. However, I do not think one should believe that the sum of the problems in Afghanistan is down to the Iranian Government. Iran has a border with Afghanistan, it has to deal with a range of problems that are exported from Afghanistan to Iran and it has a range of links with a variety of groups in Afghanistan. In many of our debates about Afghanistan we have talked about the importance of engagement with its neighbours, but I do not think that that particular neighbour is the primary source of the problem in Afghanistan, however much it has failed to play the sort of constructive role across the country that is important. One final point that should not be forgotten is that in the west of Afghanistan-in provinces such as Herat-the Iranian influence is strong but the situation is relatively peaceful.
