"MADRID (AFP) - Excessively skinny fashion models will be barred from a major Madrid fashion show later this month for fear they could send the wrong message to young Spanish girls, local media reported.

Madrid's regional government, which is co-financing the Pasarela Cibeles, has vetoed around a third of the models who took part in last year's show because they weigh too little.

The authorities collaborated with a Spanish health organisation to come up with a minumum body mass -- a height-weight ratio -- of 18 for the models.

Spanish daily ABC said it was the first time such restrictions had been imposed on a fashion show, although a recent wedding dress exhibition in Barcelona banned fashion models who took a dress size below 38 (British size 10, US size eight)."
