Who will be leading the council?

Who runs the council obviously depends on who wins seats and if it comes to forming coalitions, it's not likely we will know who all of the new council leaders are as soon as the votes are announced.

As part of our coverage of the build up to the elections, we've interviewed a number of people who think they could be leading Wales' councils for the next four years.

You some profiles of the key battles here:

Where will the parties win (or lose) it?

Labour

Labour have gone into this local election with the most to lose and their leader has spelt out just how hard he expects tomorrow to be.

In 2012 they raised their seat numbers by 200, with a total of 580 Labour councillors.

But Party leader Carwyn Jones has said that is will be has said it would be "tough" for Labour to avoid losses.

In March, he told the Huffington Post : "Council elections are just weeks away, and whilst we will be going all out to secure every vote we can, we know it will be tough to replicate our stellar results in 2012."

Labour's currently holds Wales' biggest council, Cardiff, and a swathe of other South Wales councils but keeping Cardiff is by no means a cert.

Nor is Blaenau Gwent or Bridgend and if you look at the predictions for the General Election, there are eight Labour seats at risk and they stretch from north to south Wales - so Labour will be looking at how their vote fares on May 4 ahead of their next poll on June 8.

Laura McAllister from the Welsh Governance Centre believes that Torfaen, Merthyr Tydfil and Neath Port Talbot are the only places Labour can be confident of retaining overall control.

Plaid Cymru

Plaid has more than 550 candidates standing across Wales tomorrow. Across Wales, the party has 170 councillors. While Gwynedd is its only outright they have a Plaid-led coalition in Ceredigion and a minority administration in Carmarthenshire.

After Leanne Wood's triumph in the Assembly election, the Valleys are where a lot of Plaid hopes lies, in Rhondda Cynon Taf Plaid has nine councillors. And in Cardiff, Plaid's AM and councillor Neil McEvoy has said he believes he could be council leader and thinks 30 seats is realistic (the group currently have five).

On Anglesey there are 30 councillors and 12 are from Plaid Cymru with the Independents close behind with 10. That too is a seat that Plaid hope to take on June 8's General Election.

Conservatives

In South Wales, Monmouthshire is the only authority where the Tories have a say (with Lib Dem support).

A lot of hopes have been pinned on the Vale of Glamorgan partly helped by being the constituency of Welsh Tory leader Andrew RT Davies and Secretary of State Alun Cairns.

Newport is Labour run but the Conservative group leader Matthew Evans has said "we will not be in a position to take control of the Council outright, but we are hoping to make several gains and there is everything to play for".

Lib Dems

The Lib Dems have 75 seats in Welsh councils. In their Westminster and Assembly elections they have seen a wipeout.

But, on the eve of the election they have announced their membership is at its highest ever.

They are optimistic they can take Cardiff back from Labour (the Lib Dems had a coalition with Plaid in 2012).

Swansea is also a hopeful as could be Ceredigion and Powys.

Who else?

Ukip, the Green Party and the Trade Unionist Socialist Coalition are among the other parties fielding candidate. But as you can see from the make-up of councils in Wales, there is a strong independent standing. Powys is outright independent but places like Denbighshire and Wrexham have independent-led cabinets.

There are 870 people standing in Wales as independents or others in this election.

Ukip is putting up 80 candidates but currently has no councillors.

The Greens have 78 candidates with just one seat, in Gwynedd.

What else do I need to know?
