I told the right hon. Lady in my previous answer that a £20 million budget had already been earmarked for this work. Whatever she may be reading in the newspapers about timetables, it is also the case that not just the United Kingdom but the European Union has committed itself to trying to get these alternative measures agreed by 2020. The European Commission has not entered into that undertaking and commitment lightly or without some thought and analysis of the chances of achieving it. The solution she identifies for a frictionless border on the island of Ireland would be delivered by the Government’s withdrawal agreement, so she should be urging her right hon. and hon. Friends to vote for the Government’s proposal, instead of rejecting it and therefore blocking the Brexit that her party’s manifesto commits her to.
