All 70 models taking part in the five-day event which gets under way Monday were weighed and the three were found to have a body mass index (BMI) of less than 18, the online edition of daily El Pais reported.

In 2006, Madrid’s regional government - which sponsors the show - introduced bans for models with a BMI of less than 18 from taking part.

The move followed complaints that girls and young women were developing eating disorders by trying to copy the models’ rail-thin looks.
