May I first pay tribute to the work of the HALO Trust, a British charity and the largest de-mining organisation working in Afghanistan? Tragically, 10 of its team were killed in an ISIS attack a week ago. James Cowan, the CEO, has vowed to continue their important work, and I hope that the Government will encourage the Afghan Government to improve local security so that the HALO Trust can continue that important work.
In the 1970s, we attempted to sell 100 Chieftain tanks to Iran. We took the money—£400 million—but following Iranian revolution, the tanks were of course never delivered. We need to repay that debt, because it is starting to interfere with other bilateral issues. I invite my right hon. Friend to speak to Tony Blinken, because this is to do with legacy sanctions and we need to resolve the issue.
