§ Chris Grayling
To ask the Secretary of State for Transport what recent assessment he has made of the security risks posed by(a) glass bottles and (b) minor household items, with particular reference to nail files, aboard aircraft. 
§ Mr. McNulty
As part of the heightened security measures introduced in September 2001, airports and airlines are required not to allow into an airport's Restricted Zone, or into the cabin of an aircraft, any item which could potentially be used as a weapon. The list of prohibited items, which was provided, is not exhaustive, and includes a requirement to remove from passengers any other article which the airport or airline reasonably consider might be used, or adapted, for causing injury. All of the measures in the National Aviation Security Programme are kept under permanent review.
