The Labour Party have released a line of attack against the Lib Dems and their leader Nick Clegg which I suspect will run until polling day in May next year.
The ‘You Can’t Trust Nick Clegg’ line is a classic piece of political attack against any opponent who has broken promises and the effectiveness of its deployment is usual dependent on how blatantly the party / politician in question has gone against their word. In this case, the slogan lands as heavily as a piano lobbed off a tall building.
