I am very grateful to my right hon. Friend for her words. She is absolutely right that the G20 posed a huge opportunity for the Prime Minister to share thoughts and concerns about a number of matters pertaining to the middle east. I am not aware of what happened, but I will find out whether she was able to take up such an opportunity. I was certainly able to do so when I was with the Foreign Ministers from Saudi Arabia and the Emirates and John Kerry last week. As I have said, there is a further opportunity for this House to raise those questions too. My right hon. Friend also raised the issue of the cluster munitions convention. I have invited Saudi Arabia to consider signing it as an indication of where it wants to move to in the future.
