Question to the Department for Transport:

To ask the Secretary of State for Transport, what estimate he has made of the number of staff (a) departing from his Department who accepted jobs with Heathrow Airport Limited and (b) arriving in his Department from Heathrow Airport Limited in each of the last five years.

The Department does not hold any information on the destination of employees, or their previous work history so is unable to provide an estimation or confirm numbers of staff.
