I don’t want to be unkind or discourteous to the Foreign Secretary but I say on advice, as the clerks swivel round to me, two things.
First of we all, we don’t name call in this chamber.
Secondly, we do not address people by the titles of their spouses. The shadow foreign secretary has a name and it’s not Lady Something, we know what her name is and it is inappropriate and frankly sexist to speak in those terms.
I'm not having it in this chamber. That is the end of the matter. No matter how senior a member, that parlance is not legitimate, it will not be allowed and it will be called out.
