Revellers take part in the annual Tomatina festivities in Bunol, near Valencia, on August 28, 2013
Buñol (Spain) (AFP) - Thousands of half-naked revellers will pelt each other with squishy tomatoes on Wednesday in Spain's Tomatina, a world-renowned fiesta stained this year by a row over its privatisation.
Popular with visitors from Britain, Australia, the United States and Japan, the Tomatina brings the small eastern town of Bunol to world attention once a year for an orgy of goo dubbed "the world's biggest food fight".
Mindful of safety and finances, the indebted local authorities last year began charging revellers an entry fee and hiring a private company, Spaintastic, to sell tickets.
The town hall vowed to improve safety at the wild festival, in which participants drink sangria and splash around in the red juice and pulp.
Before the privatisation around 40,000 revellers would cram into the town, quadrupling its population. Places are now limited to 22,000.
"In the past few years the essence of the Tomatina had been lost. There was no space and it was quite dangerous," Bunol's deputy mayor and top Tomatina official Rafael Perez told AFP.
"Now it is much more enjoyable and Bunol locals who had stopped attending are coming back to it."
The entry fee "has enabled us to finance the fiesta and make it safer".
- 'Corruption' slur -
This year organisers have offered 5,000 tickets free to locals, while a further 17,000 have been sold -- most via tour companies that bus revellers to Bunol and fill them with sangria and paella.
They have also launched a music festival to keep revellers in town after the one-hour tomato-pelting ritual ends at noon (1000 GMT) on Wednesday.
The privatisation of the popular and lucrative event has sparked squabbling among politicians in the town.
Spain's governing conservative Popular Party -- in opposition in Bunol -- has demanded an investigation into whether it is carried out legally by the town hall, led by the United Left party.
"We cannot look the other way when there has been a suspected case of corruption in an illegal privatisation of the festival," the PP's local spokesman Marcial Diaz told AFP.
He said his party supported privatising the Tomatina but alleged that Spaintastic "was awarded this business arbitrarily without any kind of public contract or bidding process".
The deputy mayor Perez denied the allegations, branding the PP's lawsuit "a purely political move".
"People in Bunol don't understand it. There is great anger about this," he said.
"They are soiling the image of Bunol and of the Tomatina. But we are not worried. We have most of the people of Bunol on our side."
He said that so far this year the Tomatina had brought in 170,000 euros ($224,000) in ticket sales for the town hall and a further 10,000 euros in sponsorship.
Like many Spanish towns, Bunol is deep in debt after Spain's financial crisis.
According to a survey by financial newspaper Cinco Dias based on figures from the Spanish treasury, Bunol had 5.5 million euros of debts in 2013.
The Tomatina started in the 1940s when locals brawling in the street at a folk festival seized tomatoes from a greengrocer's stall and hurled them at each other.
This year participants will throw 125,000 tonnes of tomatoes produced specially for the Tomatina despite complaints that it is a shameful a waste of food.
