There is no date yet for a by-election in Oldham East and Saddleworth but there is plenty of campaigning.
It will not be officially called until the High Court has ruled on the outcome of Phil Woolas' request for a judicial review of the decision to force him from the Commons.
But on the streets of the constituency a phoney war is already being fought.
I spent some of the weekend with the Liberal Democrat campaign which has the advantage of a candidate in place and a head-start.
In an email to supporters, Liberal Democrat HQ anticipates a by-election in early January: "There could be as few as eight working days in 2011 before Polling Day.
"That means we must win this by-election before Christmas. Please do not wait until the New Year to help out."
The campaign has had support from across the country. But the team admits it's difficult to maintain momentum when there is no election date and it's very cold.
This is even more tricky for Labour since Phil Woolas was one of their MPs and they cannot put a candidate in place until he moves on.
They are campaigning but unofficially.
In another email we've seen, Labour writes: "The Lib Dems are swamping the constituency with activists from across the country. We run the serious risk of being out campaigned if we don't rise to this challenge."
Indeed Lib Dem volunteers say they are getting a good response on the doorstep.
But they must handle it carefully.
At a Christmas fair I spoke to a few voters who were unhappy with the amount of campaigning. They didn't think it should start until the legal situation has been resolved.
I wondered during the General Election whether the Liberal Democrats had alienated some voters by putting out too many leaflets.
It seems for some, they are doing the same again.
