Thank you, Minister. Finally, I'd like to ask about the Welsh Government's membership—or, rather, absence, apparently—of the UK Energy Research Centre's steering committee. That committee is undertaking a review of energy models being used across the UK by public bodies, universities and the energy industry. The Welsh Government's absence from that committee is notable, because it would be the only UK Government body not to be represented. I'd be glad to be proven wrong on this, but given the importance of the issue, I'd like to ask: has the Welsh Government been invited to be a member of the steering group? Did the Welsh Government decide not to join and, if so, why? And finally, what institutional experience and, indeed, access to information would you calculate has been lost as a consequence of that decision to not participate in the advisory process?
