Presiding Officer, in the spirit of your oft-repeated plea that ministers and members should avoid extending such exchanges unnecessarily, I refer the member to my previous answer. However, in so doing, I point out that the convention that I referred to is so long standing that it goes all the way back to when the Lib Dems were part of the then coalition Executive. Of course, that was quite some time ago, which is perhaps why the existence of the convention has slipped from Mr Rumbles’s memory.
