The hon. Lady reiterates the point made by my right hon. Friends the Members for Chingford and Woodford Green (Mr Duncan Smith) and for Broxtowe (Anna Soubry). Sanctions are absolutely integral to this, and they are within the scope of the working party, but as I have made clear, these are early days. We will be taking advice from a number of different expert groups who will inform the decisions that the working group takes, but I want to assure her that the subject of sanctions is absolutely within scope for resolution by the working party.
