Let me be very specific: it is the policy of this Government to remain part of the internal energy market. The policy has not changed—for the same reasons, in truth, that applied before. They still apply today.
I will write with a specific answer to the question about petroleum reserves, which might be helpful. It is important to stress that it is government policy to ensure that the reserves are adequate for every eventuality. They must be stress tested necessarily through the challenges that Brexit represents. It is not our ambition to in any way put at risk what those reserves mean for the functioning of the wider energy situation in the United Kingdom. I also stress that we are—primarily in gas, certainly—dependent on imports from outwith the EU as a whole, although not primarily from Russia.
