I said on the other thread that I have no objection to formalising the role of OWL, but that I oppose the creation of a new ministry. This proposal achieves that end and I am happy to support it.
I'm not sure the Assembly needs to confirm the office-holder, for the reasons given earlier in the thread. If I recall recent discussions correctly, it was broadly agreed that even an unelected official could be recalled by the Assembly, so that strikes me as an appropriate safeguard.
