It has been reported that
The director of public prosecutions is considering a complaint that voters were misled by the Vote Leave and Leave.EU campaigns, in contravention of electoral law.
In other words, the question of whether the lies that were told amount to a criminal offence is being considered. Early days, of course, but something to be watched.
We seem to have got to the stage where politicians can tell any lie they like and get away with it because, “that’s politics”, or “people say all sorts of things in and election campaign”. I don’t know how far this will get, but it is more than time that politicians who lie suffered the consequences, including criminal prosecutions.
