We are doing a great deal, leaving aside any instruction particularly to smile, and always observing the duty of the Immigration Service to maintain firm and fair immigration control. We are continually monitoring the queues at the major airports that my hon. Friend mentioned. We have had a quality of service initiative to lead to improvements of various types. We have introduced fast-track channels for business and first-class passengers. In time for the summer season, we are introducing earlier shifts at terminals where delays can occur because of bunching of early-morning flights. My hon. Friend will also want to know that we have a scheme for authorised tour groups of expedited clearance organised by the Immigration Service.
