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.
The newly-elected Police and Crime Commissioners will start work in their four force areas today.
Christopher Salmon (Dyfed Powys), Ian Johnston (Gwent), Winston Roddick (North Wales) and Alun Michael (South Wales) were elected last Friday.
The new commissioners will replace police authorities and will set out local policing priorities, decide how forces' budgets should be spent, and have the power to appoint and dismiss Chief Constables.
The Electoral Commission is investigating the low turnout for the Police and Crime Commissioner elections. In one polling station in Newport not a single vote was cast and in Gwent overall turnout was just 14.3%.
Two Independent candidates were elected in Wales. Ian Johnston says he just wants to get on with the job. Hannah Thomas reports.
The Electoral Commission says it will conduct a review of the PCC elections, warning that record low participation levels of well below 20% were "a concern for everyone who cares about democracy".
Newport Council has confirmed to me that only one polling station in the city had seen not a single voter yesterday. It had been thought there was a second. Newport council won't tell me which polling station it was but a reliable source confirms it was at Malpas Cricket Club.
The club's previous claim to fame had been one of its most notable members, the late act Desmond Llewellyn who played Q in the James Bond films. He was from Malpas and boasted he wore a MCC (Malpas Cricket Club) tie in all the Bond films.
Meanwhile Labour MP Wayne David drew my attention to Tir y Berth in Caerphilly. He told me nobody voted there either.
"Yes, it was a low turnout, but the mandate comes with the office", newly-elected Police & Crime Commissioner for Dyfed Powys Christopher Salmon told Kevin Ashford.
"100% of people had a chance to vote. Clearly, there are lessons to be learnt, and I'm not under any illusions about that."
"It happens at an unusual time of year - that will change in future. It's the first time for the post, and it's taken a lot of explaining to people".
Former Cardiff South MP Alun Michael has been successful in his bid to become the first Police & Crime Commissioner for South Wales.
Mr Michael won in the second round, defeating Independent candidate Mike Baker with 72,251 votes to 60,784.
The polling station in Newport which saw no voters in the PCC elections was at Malpas Cricket Club.
There is another zero-vote polling station in Newport. I’ve just filmed there but need confirmation I have the right place.
Labour's Alun Michael faces off against Independent candidate Mike Baker, as second preference votes are counted in the South Wales Police & Crime Commissioner election.
After the first round, the votes were as follows:
- Mike Baker (Indepedent) - 46,264
- Caroline Jones (Conservative) - 20,913
- Alun Michael (Labour) - 66,879
- Tony Verderame (Independent) - 8,378
