My hon. Friend asks an important question. What we have done so far has focused on the Egyptian and Tunisian borders, where Britain has led the way in supplying tents and blankets and in flying people back home to Egypt, because we want to ensure that a bad humanitarian situation does not become a humanitarian crisis. His point about access to western Libya is vital. Humanitarian aid agencies do not have access to all areas; they absolutely should have, and the Libyan authorities should see to that straight away.
