If Labour wants to rewrite the rules it needs clearer policies

You can applaud some of John McDonnell's plan but some parts are vague and others just plain odd

Let's start with the good bits in shadow chancellor John McDonnell's speech on "rewriting the rules of our economy". Forcing big accounting firms to split their auditing and consulting units is justified: current conflicts of interest are too great. One can applaud the push to get workers on to boards. And enhanced voting rights for long-term shareholders is an idea worth exploring.

If McDonnell had stopped there, he would have had a worthwhile package of reforms. But he moved on to territory that ranged from radical to vague to plain odd.
