It’s Day Three of the (to my mind doomed) High Court challenge on Article 50. But the Indy has a nice new line on Parliamentary approval. It has dug out a 2010 Government promise under David Cameron that referendums “cannot be legally binding”. Then minister Mark Harper responded to a Lords report that referendums are “advisory”, stating “The Government agrees with this recommendation.” Nicky Morgan, Dominic Grieve and Ken Clarke have all seized on that one. And Norman Fowler, now Lords Speaker, upset several Eurosceps on Daily Politics yesterday by saying that the Great Reform Bill was “just like any other piece of legislation”, adding that peers can “at times…vote down something that has come from the Commons”.
