One of the axioms of communication is that nobody ever had a communication problem who didn’t have a real problem. Liz Truss and her diminishing band of supporters have been trying to argue that her political problems are really just flaws in presentation but they are kidding themselves. The mood of the Conservative Party, as its delegates gather in Birmingham for their annual conference, is grim. Ms Truss has a serious problem and so does the party she leads. Her problem is that many of her MPs already want her gone.
