As we have repeatedly made clear, this is an insurance policy no one wants to use. It is needed in case the future relationship is not ready at the end of the implementation period to ensure that there is no hard border. However, as we have also made clear, it is not the only option. There is a possibility of a short extension to the implementation period. It has also been made clear in both the withdrawal agreement and political declaration that both sides will consider how facilitative arrangements and technologies can be used to avoid a hard border on the island of Ireland. There are other options that we will all be exploring rather than the backstop.
