Mr Morgan said the BNP was "brainwashing" youngsters

Dubbed "all but politics-free," the event will include a closing address to the teenagers by BNP chairman Nick Griffin and Young BNP chairman Mark Collett.

But the first minister, who said there was speculation the camp would be held in Wales, said the party was using the event to recruit fascists.

"If this is true, I think I speak for everyone in expressing my total revulsion at the very idea that Wales would be playing host to Nick Griffin brainwashing the more gullible young people," he said.

"The BNP is pretending to be putting on a fun weekend, but are trying to recruit future fascists."

First camp

Said to include paintballing, archery, football, outdoor pursuits and singing, the camp event is the first of the party's new youth camps.

A BNP spokesperson said: "We're still organising it and getting it ready.

"We're not releasing details to members of where it's going to be held until nearer the time.

It follows a BNP "family festival" in August in the tiny village of Llanerfyl near Welshpool, Powys, on land adjacent to Nick Griffin's home.

The 'Red, White and Blue' event was held on a farm owned by the BNP leader's neighbour and included face-painting and entertainment as well as political talks.

Dyfed-Powys Police kept rival Anti-Nazi League protestors away from the rally site over fears the two groups could clash.

Before that event, Mr Morgan also attacked the party's "self-destructive" philosophy as "alien to everything we stand for in Wales."

Location unknown

An advert for Camp Excalibur on the British National Party's website says the event "will be a cracker, weather permitted."

It adds:" Camp Excalibur is not just a male event. There is plenty to do for young women as well, and several girls are helping to organise the weekend."

Nick Griffin lives near Welshpool

The exact location for the camp is not specified, but visitors are invited to book places by writing to an address in Welshpool, near to the site of the earlier rally.

Mr Morgan said: "The fact that the only BNP candidate standing in Wales at the recent general election got the lowest votes of his party anywhere in Britain was testimony to Welsh good sense."

Nick Griffin's father, Edgar, was expelled from the Conservative party after more than 50 years in August after answering a telephone at his Welshpool home on behalf of the BNP, for which his wife is an active member.

Dyfed-Powys Police in Welshpool said they were not aware of the plans for the camp but would expect a police presence at the site if details were confirmed.
