I thought the letter was interesting in that regard. The truth is that Britain’s membership of this organisation is different from that of other countries. As the document sets out, we are not in the euro, we are not participating in Schengen, we keep our own border controls, we choose whether to participate in measures of freedom, security and justice. We opted out of the justice and home affairs area, and now we are opted out, as it were, of ever closer union. Our membership is different, and we need to make that case strongly as we go forward.
