Delyn MP and Shadow Police Minister David Hanson has described the turnout in the election as "shambolic".
"The buck stops with the Goverment" he said, as he watched the election count in Flintshire.
'"They refused a free post and they refused to promote this in an effective way".
A 'detailed inquiry' will held into the Police and Crime Commissioner polls. In Gwent, only 14.3% voted - many places saw no ballots at all.
Independents take North Wales and Gwent, while the Conservative candidate wins in Dyfed Powys. Labour wins in the South Wales region.
Counting will get underway later this morning, in elections for new Police and Crime Commissioners for each of Wales' forces.
