You’ve hit the nail on the head. This is merely limelight-grabbing from a politician who knows that he is despised by his own colleagues. He will be kicked out of Plaid very soon hopefully. All the same I am glad that the issue has been raised as it deserves further investigation.
I did a lot of work with the Stop Hinckley group a few years ago and the construction of a new nuclear power station is the big issue, not the mud.
