Richmond Park is in one one of the wealthiest and most privileged parts of Britain and would have most to lose from a victory by a Labour Party with decent principles, so the only surprise would have been so see Labour advance in any way there.   
Of course this vote was about the new runway - yo only have to spend four minutes (the length of the time gap between passing planes) to realise that.
This proposed runway is a fine example of the disinterest this Government has for the health and comfort of those they govern - profit before people, every time.
