§ Dr. GibsonTo ask the Secretary of State for the Environment, Transport and the Regions what data he collates on the numbers of air passengers developing thrombosis on long distance and short distance flights. [134421]
§ Mr. MullinThe data are not collated centrally. Such data would be difficult to obtain as any passenger developing thrombosis is usually likely to do so a number of days or weeks after the flight has taken place.
