POLITICIANS will make a final pitch to voters in target seats today on the last day of the General Election campaign.

Welsh Labour leader Carwyn Jones and Welsh Secretary Peter Hain will cover 400 miles in what Labour calls its "decision day dash’’.

The pair started in Newport this morning with First Minister Mr Jones heading west to Cardiff and Carmarthen, and Mr Hain going north.

Conservative David Cameron is expected to make a stop in Mid-Wales during a tour of the UK.

Welsh Liberal Democrat leader Kirsty Williams will be in Wrexham where the party hopes to see local candidate Tom Rippeth elected.

And Plaid Cymru leader Ieuan Wyn Jones will lend his support to nationalist candidate Myfanwy Davies in Llanelli.

The latest YouGov poll of Welsh voters for ITV Wales last night showed Labour clawed back some support in the latter half of the campaign.

But at 35%, up two points on last month, its share of the vote in Wales would be well short of 2005 and at its smallest in a general election since 1918.

The poll showed the Conservatives returning to second place on 27%, ahead of the Liberal Democrats who fell six points to 23% since April. Plaid Cymru remained fourth with 10%.

It came at the end of a day when the Tories accused Mr Hain of desperation for sending out signals on tactical voting.

Speaking to journalists in Cardiff, he urged voters in key marginal constituencies where the election would be decided to back Labour.

But he added: "What happens in other constituencies where there isn't a Labour MP and we are not challenging to win and where there is no Conservative-Labour battle to determine the future of Wales, people need to vote intelligently, of course they do.

"They need to vote intelligently right across Wales, but I want everybody to vote Labour.’’ With large numbers of voters still undecided at this late stage, Mr Hain predicted the outcome could be determined at the very last moment.

"I can even see voters going into the polling station, not clear which way they are going to vote, their pens hovering over the ballot paper and then finally coming down for Labour.’’ First Minister Mr Jones said: "Tens of thousands of people in Wales still have not finally made their minds up. I believe this will be a last-minute election like 1992.

"Now is the time for the decent anti-Tory majority in Wales to come together to keep David Cameron out.

"I make a direct appeal to all those who do not want a Tory government - don't let Cameron in by the back door. Vote Labour tomorrow.’’ Shadow Welsh secretary Cheryl Gillan said: "In their desperation to cling on to power, Peter Hain and his Labour colleagues are making a last-ditch appeal to voters they have taken for granted for far too long.

"They tried frightening them, they tried threatening them and, when that hasn't worked, they tried begging them to change their vote.’’
