My Lords, I do not agree that there will be a difficulty. The announcement suggests that Mr Frost will take up his appointment around the end of August, and, as the noble Lord said, there will be a period of handover. Mr Frost will remain chief negotiator for the EU talks until agreement is reached, or until they end. That will remain his first priority. As I have already said, he will also be ready to answer to Select Committees of the House in that period.
