This is like the bully in the playground not only demanding a penalty for a non-existent foul, but also insisting that there should not be a keeper when he takes it. Unless the keeper agrees to give him an open goal, he'll take his ball home.
This is the second stage of a hardening of London's attitude towards the brand spanking new LCO's. Before last week there had been some tension between AM's and MP's, most notably the MP's complaints that both ends of the M4 should be reviewing potential LCO's at the same time instead of the Assembly passing judgement before London. The Child smacking/abuse threat this weekend comes hot on the heels of a Welsh Office "warning" last week that the Assembly should not "overpromise" the number of laws it would deliver.
The new message from London is quite clear then:
1. We'll give you enough so that we are be able to say there's no need for a referendum, but don't think of asking for much more.
2. If London don't like, Cardiff can bugger off.
