The request in question 298409 was about representations received from hon. and right hon. Members of each party in favour of (a) a third runway at Heathrow airport, (b) a second runway at Gatwick airport, (c) further expansion of Stansted airport and (d) a new airport in the Thames estuary. No time period was specified. As my 9 November answer explained, no such records are held centrally. To seek to obtain the information would therefore require an exhaustive search of both electronic and paper records across the Department for Transport at least as far back as 2002 when options for airport development were consulted upon. Such an exercise would well exceed the £750 threshold in Cabinet Office guidance for written questions.
