I rise to support new clauses 3 and 57. I commend my hon. Friend Matthew Pennycook and my right hon. and learned Friend Ms Harman for their speeches. The one thing I would add to the forceful case made by my right hon. and learned Friend is this: when the Exiting the European Union Committee took evidence from representatives of Brits living abroad, one might have expected them to make the argument that has just been advanced, but they said the opposite. They said that Britain should give a unilateral commitment now, because they felt that doing so would ease the process of negotiation.
