My hon. Friend makes an important point, which is that in spite of the difficult decisions we have to take, it is right to keep increasing the aid budget. Sadly, what is happening on the Egyptian and Tunisian borders with Libya shows how important that decision is. As the UN Secretary-General, Ban Ki-moon, said last night, there are serious implications of a growing humanitarian crisis. The information is that some 162,000 people have crossed the land border so far. We have sent technical Department for International Development teams to both the borders and yesterday we flew in tents for 1,500 people and blankets for 36,000 people. I can tell the House that today we are launching a UK operation to airlift several thousand people back to Egypt from the Libyan-Tunisian border, with the first flight scheduled to leave the UK later today. It is vital to do this; those people should not be kept in transit camps if it is possible to take them back to their home. I am glad that Britain can play such an important part in doing that.
