They can't withdraw the names from ballot papers at this stage. They can, of course ask electors to vote for another candidate but I cannot see how that would work in reality seat by seat.
My point was that all the organisations calling for mass tactical voting ( et al Carol Vordeman) are doing it in the belief that it is purely an anti Tory measure when this demonstrates that is not necessarily true.
PS congrats on your campaign. I have been there many times before.
The new yougov MRP poll for sky suggests Labour will only have a 194 seat majority. This system gives a constiuency by constiuency extrapolation for those nerdish enough.
