§ Mr. Spring
To ask the Secretary of State for Foreign and Commonwealth Affairs what procedures are in place 535W to monitor whether a person, subject to an international travel ban by either the EU or the United States, transits via a UK port en route to another destination. 
§ Beverley Hughes
[holding answer 17 June 2002]: I have been asked to reply.
We are not aware of any nationals, subject to a travel ban, passing through the United Kingdom to other countries. But at major United Kingdom airports, only passengers who present themselves at the immigration control seeking entry while in transit would come to the attention of the Immigration Service. Many others will remain airside and travel on in direct transit to their destinations without seeking leave to enter the United Kingdom.
The United Kingdom Immigration Service is responsible for enforcing the travel bans. Immigration officers at ports have been instructed not to grant entry to those identified as being on the ban lists.
