It's more evidence of Zac's unhappiness in the Tories and debate continues over whether he will decamp to UKIP, become an independent conservative, or even (Sunny Hundal has suggested) stand as Mayor of London should Boris resign - a role in which he could take an independent stand from Tory policy and fight against the third runway.
In any event it seems increasingly unlikely that he will be a Conservative candidate in or around Richmond in the next general election.
Interesting times in Ham Common...
Here's a BBC news report on the airport issue and what Zac says is even more interesting. On the issue of the third runway he says
'IN THIS AREA I wouldn't stand as a Conservative on that manifesto'
Maybe Mary Reid (below) is right - and he's jumping ship to another constituency...
