As you know, you will have the unequivocal support of the Labour Members in opposing a third runway at Heathrow, and a sixth terminal.
In assembling the case for that you will have to respond to the concerns of the Corporation of London and the City financial services. You say London's that position is enhanced and not threatened by the number of destinations that can be achieved. You will also have to answer the many Londoners with overseas connections who see cheap and accessible travel to other parts of the world as part of the deal they have in living in London. They are fairly substantial cases. It does not alter the fact that we agree with you, but how are you going to address those concerns?
