Not electoral suicide to lie
If you won't get caught until after the election. It would be very possible for Labour to have got this information illicitly, then lie about it, knowing that no report will be completed until well after the election result in known.
However I'm not sure that's the case here. It's just that a lot of people have had breast cancer, and this card targeted a lot of people.
Although it does make me wonder if this was the effect Labour intended to achieve. After all, if there is huge controversy, it will get their message played a lot more on all media, and they get a claim, that so far as I'm aware isn't true, about Conservative policy spread - because it's hard to do 2 things at once in the media.
Labour's campaign has been pretty solidly negative. While I'm always prepared to believe cock-up before conspiracy, Labour's leadership do have a solid record in recent years of media dirty-trickery, deployed against opponents both inside and outside the party...
On balance, I think I'll go for cock-up.
