Plans for the 2009 Royal Lancashire Show have been scrapped.
The move to cancel the event for the second year in a row throws doubt over the future of the historic event, which has been plagued by problems.
The Royal Lancashire Agricultural Society, which organises the annual event, said it had "no alternative" to quit the site at Myerscough, owned by the Duchy of Lancaster, because it could not host the show in bad weather.
Last year's show was cancelled hours before it was due to open when downpours turned the site into a muddy mess.
The RLAS has sent letters to its members, claiming the Duchy's agents had "made it clear that they were not prepared to invest any further capital in the development of the site at South Planks Farm (Myerscough), or to undertake the promised development of buildings there."
The statement, on behalf of Countywide Events Limited, a subsidiary of the RLAS, added: "Time is now too short to find an alternative to the Myerscough site, despite a number of service contracts already confirmed.
"The site is not conducive to a quality event as it is unable to withstand the effects of adverse weather.
"Given that weather conditions are important, we really have no alternative but to lose this year's show."
The three-day event in 2007 was scrapped after relentless rain waterlogged the showground in the grounds of Salesbury Hall, in Ribchester, near Preston.
Unseasonal downpours also forced organisers to cancel the third and final day of the show in 2003 because the ground turned into a quagmire.
And between 1975 and 1979 the show was not held at all, with financial problems a significant factor.
