Demand will be even higher than usual after Wales' 2005 Grand Slam

Tickets costing �30 are being offered for �145 in a blow to the Welsh Rugby Union's attempt to prevent tickets being touted online.

The WRU has promised action against clubs after it claimed tickets they received went up for sale. It is not known if any clubs are involved now.

The Millennium Stadium's Paul Sergeant said profiteering was completely wrong.

We allocate the tickets in the honest belief that the person is going to go the game Phillip Cunningham, Canton RFC

Earlier this year the WRU announced action against 11 clubs after announcing what it called a "tough new ticket policy".

Clubs which sold tickets online were warned that they could be refused them in future, with the union saying it wanted to ensure that they went to "true rugby supporters and not sold to the highest bidder".

The clubs which had been previously named by the WRU were Aberavon, Blaenavon, Caldicot, Cilfynydd, Cwmgwrach, Gorseinon, Resolven, Loughor, Pontllanfraith, Narberth and Abercrave.

Phillip Cunningham, fixtures secretary of Canton RFC in Cardiff, who are not involved, said clubs like his would be unable to survive without its ticket allocation.

'Out of control'

"It's an essential piece of revenue which every club depends on for survival, so it's vastly important," Mr Cunningham told BBC Radio Wales.

"I think it would be right for the WRU to take action against a club if the club were found to be assisting or supporting that course of conduct.

"We allocate the tickets in the honest belief that the person is going to go the game - if they do something else with them, then if we were to find out then we would take action to be penalised for someone's individual greed."

They are taking away the opportunity for genuine supporters through the clubs to buy tickets Paul Sergeant, Millennium Stadium, on internet 'touts'

Chris Clarke, chairman of the Welsh Premier League clubs and secretary of Cross Keys RFC, said his club took great care over ticket distribution, with all going to "bona fide members and sponsors of our club."

But Mr Clarke said once tickets went outside the clubs they were "out of control."

Mr Sergeant, the Millennium Stadium's chief executive, said: "It's completely wrong for people to profiteer.

"They should be going to bona fide homes - not to people who are profiteering in this way - they are ticket touts."

"They are taking away the opportunity for genuine supporters through the clubs to buy tickets. People that sell tickets on eBay are ticket touts."

Mr Sergeant said the WRU recognised that the revenue for clubs from tickets was crucial, and was working with them.

"They do sell them in good faith, but the club is the only link we have as we follow the ticket sale process through with the eventual user. So the club has to work with those people to stop them selling tickets on the internet."
