Peter Lilley: While welcoming my right hon. Friend’s calm, considered and thorough preparations before triggering article 50, does she agree that a speedy conclusion of the subsequent negotiations will be in this country’s interests, both to put an end to damaging uncertainty and because, according to the Office for Budget Responsibility, every week’s additional delay in leaving the EU costs this country £250 million net per week?
Theresa May: As I said in an earlier response to the Leader of the Opposition, the treaty sets out a potential two-year process of negotiations. For how long, over those two years, it is necessary for the negotiations to take is a matter for the progress of those discussions and talks. My right hon. Friend makes a very valid point that the sooner certainty can come the better that will be for business, but we need to make sure we are getting the right deal for the United Kingdom.
