I thank the hon. Lady for her question. She raises a very important point. The reality is that the international norms that reflect, recognise and call for the safeguarding of peaceful protest apply across the board. We do make those points to our Iranian partners, but, of course, there is a very clear obligation under the Vienna convention on diplomatic relations about the way that ambassadors and diplomatic staff are treated. This is crucial, not least because if we cannot have confidence that our diplomatic staff and missions are respected, we cannot engage in the kind of diplomacy that we need to charter a peaceful way forward.
