Re: What was the "dysfunctional and childish behaviour"
It would have helped if the article had a link to the report - https://www.nao.org.uk/wp-content/uploads/2015/11/Early-review-of-the-Common-Agricultural-Policy-Delivery-Programme.pdf
The relevant paras are at pp 28 - 29. Of course "childish" isn't actually mentioned in the report. I suspect the members of the committee have access to a good deal more information than is in the report itself.
I like the raising of the question as to why people are still in post. It's time to end the culture of people remaining in positions of responsibility for such failures.
