WE ALREADY knew the Welsh Government had made a total mess of the Circuit of Wales - the drawn-out saga has been well catalogued in the pages of this publication.

But just how wrong they got it wasn't entirely clear until this week's report by the Assembly's Public Accounts Committee.

The report paints a pretty damning picture of Wales' economy department, which made a catalogue of errors during the development of the scheme including poor record taking and not looking properly into the relationship between companies involved in the project, meaning Michael Carrick, the man behind the application, was effectively able to pay himself.

Former economy minister Edwina Hart apparently wasn't even informed of some of the decisions the department made in relation to the scheme and press releases were found to be incorrect - which hardly speaks volumes about how much we really know about how our money is being used.

Lest we forget, £9.3 million of our money went towards this project before they pulled the plug - that's £9.3 million which could have been used for more hospital beds, to help people get on the housing ladder or take some of the debt burden off Welsh students, spent on literally nothing.

This is the department responsible for a massive chunk of public spending, and we need them to be better than this.

But this isn't the only thing they've been getting wrong.

The M4 relief road was first proposed when I was in primary school, and I'm now in my 30s - and that's yet to get off the ground.

The ongoing delays and overspend on the Heads of the Valleys work - which neither the Welsh Government nor contractors Costain are terribly keen on taking responsibility for - is yet another example of just how wrong these things are going.

One would hope the Welsh Government takes this report to heart and makes some real changes to stop anything like this happening again.

But will they?

Governments as a whole don't have a great record of learning from fiascos like this.

As I write this the company who will take over the running of rail services in south Wales - and the South Wales Metro - from Arriva Trains Wales for the next 10 years is about to be named.

I sincerely hope in a decade's time we're not reading another report on why that all went so wrong.

But I won't be surprised if we are.

It's entirely possible pulling the plug on the Circuit of Wales was the right thing to do - there were certainly questions to be asked about how exactly the company behind the scheme was using the money it was given, such as spending £300,000 on a chassis manufacturer which went bust few years later.

But the way it was done leaves much to be desired.

- The unending comedy of errors that is Ukip Wales continues, with cartoon buffoon/elected politician Neil Hamilton ousted as Assembly group leader after two years of mishaps, defections and resignations.

In his place has stepped South Wales West AM Caroline Jones - by all accounts a more measured political speaker and certainly less prone to making misogynist jokes in the chamber, but largely untested.

How she'll fare going up against Carwyn Jones during First Minister's Questions each week, not to mention keeping control of the proverbial herd of cats that is the Ukip Assembly group, remains to be seen.

And with Mr Hamilton apparently gearing up to attempt to re-take the leadership, she'll have to be ready to defend the role she's only just won.

I don't envy her.
