I will just complete this point.
The EEA excludes agriculture and fisheries, which presents a problem in relation to the solemn commitment to no hard border in Northern Ireland. When I went to the border between Sweden and Norway, there was infrastructure, checks and controls—not for people, but for goods. The EEA also provides very little flexibility on the four freedoms, including freedom of movement and the way in which single market rules are implemented. Some say that those challenges can be overcome. I will continue to listen to those arguments, because there is no doubt that, in addition to a customs union with the EU, we need a strong single market deal, but I do not think we can ignore those challenges.
