Diolch, Llywydd. Cabinet Secretary, despite being set up in 2013 to deliver greater value for the Welsh taxpayer, the Wales Audit Office has been critical of the National Procurement Service. Now, by anyone's estimation, it has comprehensively failed to deliver the intended savings in public spending. In 2016-17, it only generated about 60 per cent of the savings expected and, worse still, it made a loss of around £2 million, in both 2015-16 and 2016-17. So, can I ask why the Welsh Government's flagship policy for improving public procurement in Wales has failed so badly?
