BNP leader Nick Griffin

Nick Griffin, leader of the BNP, told BBC Wales News Online that the party would be standing in one south Wales seat.

However, he said the party had now abandoned plans to fight a north Wales constituency as well.

Mr Griffin would identify neither the seat in question, nor the name of the candidate, because he said he did not want to "wind things up" with opponents.

He also confirmed that the BNP did not plan to put up any candidates in the five regional lists, where AMs are elected by proportional representation.

The party had appealed for �800 in donations to fund a candidate in a north Wales seat, where it said it already had "a very good local candidate" willing to stand.

Racial tensions

That had prompted angry criticism from North Wales Plaid Cymru AM Janet Ryder.

But Mr Griffin, who lives in mid Wales, said the party had now decided to concentrate its efforts on the seat in the south.

Nominations for assembly candidates close on 1 April.

Last year the far-right party had success in Lancashire, winning a seat in Blackburn and three in Burnley, one of several northern towns where racial tensions sparked rioting in 2001.

It now has five councillors - out of about 20,000 overall - in England, but none in Wales.

The party is also considering fielding candidates in the Scottish parliamentary elections.

Mr Griffin has said the BNP would attempt to capitalise on alleged concerns over asylum seekers in Scotland.

Last October the party said it would fight elections in Northern Ireland for the first time, fielding a candidate at the next European elections.
