So the day after I launched the "Pay It Back" campaign, David Cameron has done pretty much exactly what I suggested for his own MPs (upon pain of being banished from the party). Fair play to him.
It will be interesting to see how the other parties respond to this and I fear there are still dubious claims to come out but if the other parties do follow suit then this could be one of the shortest campaigns ever!
However, we are not there yet. Please help us keep up the pressure by signing the petition and tweeting about it (#payitback). The more the public make their feelings clear like this, the quicker the other parties will do something about it.
