Question to the Foreign, Commonwealth & Development Office:
To ask Her Majesty's Government what assurances they have received from the government of the United States that the permitted airport Homeland Security checks are random and not based on racial and other profiling.
US airport security checks are a matter for the US authorities. The US Department for Homeland Security has established mechanisms for anyone to submit a complaint if they feel they have been subject to discriminatory checks at US airports.
