We have a widespread effort to make sure we provide protection to our citizens, both in the UK and in other countries. We do extensive security liaison work with other countries, including in the region affected. I am very grateful to all the countries we work with for the co-operation and support they provide us with in this important work. It is in all our interests that we continue to maintain aviation and tourist flows and to provide the economic benefits to all parties that good aviation brings. We will do everything we can to work with those partners to make sure we have as safe an aviation sector as we can.
