Latest Welsh Barometer Poll

Our poll also asked voters to rate how much they liked -or disliked- the leaders heading their parties UK and Welsh election campaigns. When the likes and disliked were averaged out, no-one achieved even 50% likeability. Ed Miliband and Leanne Wood were the two most popular -or more accurately, the least disliked.

Here's how the leaders of the Welsh election campaigns rated:

• Leanne Wood (Plaid Cymru): 47%
• Kirsty Williams (Liberal Democrat): 41%
• Stephen Crabb (Conservative) 37%
• Owen Smith (Labour): 36%
• Pippa Bartolotti (Green): 35%
• Nathan Gill (UKIP): 30%

And the UK leaders:

• Ed Miliband (Labour): 47%
• David Cameron (Conservative): 40%
• Nick Clegg (Liberal Democrat): 40%
• Natalie Bennett (Green): 39%
• Nigel Farage (UKIP): 35%

The final poll of Welsh voters before tomorrow's election shows Labour maintaining their lead over the Conservatives in Wales, with Plaid Cymru edging just ahead of UKIP. Liberal Democrat support is slightly up and the Greens are down, compared with the last poll three weeks ago.

The exclusive poll for ITV Cymru Wales puts Labour on 39%, the Conservatives on 25, Plaid Cymru on 13, Ukip on 12 and the Liberal Democrats on 8%. The results show a slight increase in support for Plaid Cymru and the Liberal Democrats over the last two weeks, with the other main parties each down 1%.

Welsh Labour's Owen Smith has welcomed the findings of the latest Welsh Barometer poll.

The latest Welsh opinion poll shows Labour maintaining its lead in Wales. For the first time, the results of the Welsh Barometer Poll have been weighted to reflect how likely people say they are to vote.

• Labour 40%
• Conservative 26%
• UKIP 13%
• Plaid Cymru 12%
• Liberal Democrats 6%
• Green 4%

The figures show little change since the last two Welsh polls, which were both carried out just before the televised debate by party leaders.

• YouGov polled 1,143 Welsh adults for ITV Cymru Wales and Cardiff University, 13-15 April 2015.

Welsh voters seem in no doubt that health the is the most important political issue at the moment, according to a YouGov poll for ITV Cymru Wales. Concerns about the NHS are likely to have a big impact on how people vote in the Westminster election, although it's the responsibility of the Welsh Government.

People were asked to name the most important issues facing the country. Here's their top four:

• Health 52%
• Immigration & Asylum 49%
• The Economy 46%
• Welfare benefits 27%

Next, they were asked what were the most important issues facing them and their families, producing a rather different top four concerns:

• Health 47%
• The Economy 39%
• Pensions 27%
• Welfare benefits 20%

Immigration came sixth on 18%, just behind tax on 19%. In general, supporters of all parties broadly agreed about the issues facing the country and themselves. The notable exception was UKIP supporters. 85% of them listed immigration as an issue for the country, more than twice as many as picked any other issue.

50% of UKIP voters also saw immigration as an issue for themselves and their families, again making it their main concern.
