I have added a little on it. I am no expert either, so I took all the facts either from the Wales referendum, 1979 article or from the BBC. There's a couple of recent(ish) interviews with him where he still expresses doubt about the Assembly, in a "well, we have it now, so we'd better make the most of it" way, but I couldn't see an appropriate place to mention those. I don't know how closely connected the no vote was with the 1979 election results (by comparison with, eg, "winter of discontent", general swing to the right in several countries) so I omitted that.
