Paragraph 76 of chapter 1 is ambiguous. It states that we will seek reciprocal mobility arrangements, but it does not say when. Will the Secretary of State give an absolute assurance that any preferential treatment given to EU migrants will not be part of a withdrawal agreement but will be entirely in the hands of this Parliament post Brexit? This is a vital point. The people voted for Brexit because they want to control migration. They do not want to be sold down the river on this point as the negotiations proceed.
